Oo-Umai Japan · Maid Crew Ag+ Silver Ion antimicrobial tech 100-day no-questions returns Discreet plain-box shipping Buy 2 @ $37.99 each (−5%)
Your waifu deserves a proper cooldown. Three-piece Oo-Umai cleaner crew — foam wash, drying stick, fragrance powder — built with Ag+ Silver Ion technology that even your roommate's chemistry degree would approve of. The "Assassin Edition" maid-waifu key art is the apology card for what you just put your $179 Magic Eyes through. Made in Japan. Ships discreetly. Triples the lifespan of every onahole you own.
Why an onahole owner needs all three (not just one)
You spent $179 on a Magic Eyes Pure Bride. Or $89 on a Tomax. Or anything north of "Amazon impulse buy." Then you went to clean it with dish soap and a paper towel and wondered why she started smelling weird at week three. This is the kit that's supposed to be in the drawer next to her. Foam cleaner gets her actually clean. Drying stick gets the canal bone-dry so mold doesn't move in. Cleaning powder — with Ag+ silver ion — restores the silky finish, kills bacteria, and leaves a faint Japanese fragrance instead of "TPE that's been damp for four hours." Buy them separately and you spend $75. Buy the Assassin Edition crew and you spend $39.99. The maid art is free.
What's Ag+ Silver Ion, and why is it on the box?
Silver ions (Ag+) are an antimicrobial agent. The same tech is in hospital wound dressings, athletic socks, and high-end Japanese sex-toy care lines. It binds to bacterial cell walls and prevents them from reproducing — which is the entire game when you're storing a damp TPE onahole between sessions. Oo-Umai infuses Ag+ into both the foam cleaner and the cleaning powder. You get an actual antimicrobial cycle, not a rinse-and-pray. Your roommate's chemistry degree would approve, assuming you ever told them what the powder is for. Which you won't.
Squirt Blaster alone vs the 3-in-1 Assassin crew — pick your tier
Squirt Blaster alone (OH-OT-100)
The "I just bought my first onahole" pick
$19.99 · 1 component (foam cleaner only) · rinses post-session, kills the slick lube residue. Fine if your onahole was $30 and you accept she's a 4–6 month investment. Doesn't dry the canal. Doesn't restore the silky finish. No Ag+ powder. No fragrance. The bare minimum.
3-in-1 Assassin Edition (this page, OH-OT-135)
The "I own a Magic Eyes and want 3 years out of her" pick
$39.99 (was $75) · 3 components: foam cleaner + drying stick + Ag+ silver ion fragrance powder. Full clean-dry-preserve cycle. Maid-waifu "Assassin Edition" key art on the box. The actual care kit Japanese onahole forums tell you to buy. Doubles or triples lifespan vs. soap-and-water. Buy 2 sets at $37.99 if you rotate multiple onaholes.
Real talk: if your onahole cost more than $50, the Squirt Blaster alone is leaving money on the floor. The Ag+ powder is the part that makes the TPE last. Just saying.
What's in the Assassin Edition box
- 1× Washing Fluid (Liquid Foam Cleaner) — pump-foam dispenser, ~200 ml (6.76 fl oz). Lather, swirl through the canal, rinse with warm water. Lifts lube, sweat, and the stuff you don't want to name.
- 1× Drying Stick — absorbent core, ~7.1 in (18 cm) long. Insert + shake + rub with a towel until the canal is bone-dry. The single most under-used tool in onahole care.
- 1× Cleaning Powder (Protection Powder) — ~50 g (1.76 oz) of Ag+ silver ion infused powder with a light Japanese fragrance. Dust the canal, store her, done. Restores the original silky touch and keeps bacteria from setting up shop.
- "Assassin Edition" maid-waifu key art — canon Oo-Umai character card on the front of the inner box. Collector-grade, ships inside a plain outer box.
- Care card in English — ADP-written 3-step instructions in case the Japanese pictograms are doing too much.
Use her properly in 3 steps
- Rinse + foam wash. Right after the session: rinse the canal with warm water, then pump 2–3 shots of the Liquid Foam Cleaner inside, swirl gently, rinse it out. Don't use dish soap. Don't use hand soap. Don't use shower gel. You bought a $179 onahole. Use the cleaner that was designed for her.
- Drying stick + towel. Insert the drying stick all the way in, shake gently, then rub with a clean towel for 30–60 seconds. You want the canal bone-dry — not "kinda dry." Moisture is what kills TPE, not use. This is the step everyone skips and then complains on Reddit that their onahole "got sticky in two months."
- Ag+ powder + store. Dust a small amount of the Cleaning Powder onto the exterior and lightly inside the canal. The silver ion does the antimicrobial work; the powder restores that out-of-the-box silky finish and leaves a faint Japanese fragrance. Store her in her original Oo-Umai or Magic Eyes box, away from sunlight and other silicone toys. Done. Three minutes.

FAQ — the questions you almost asked
Do I really need all three components, or can I just use the foam cleaner?
You can survive with foam cleaner alone. You can't preserve a $179 onahole with foam cleaner alone. The foam wash cleans. The drying stick removes the moisture that kills TPE. The Ag+ powder kills bacteria + restores the silky finish. Skip the dryer and powder and your onahole lasts 6 months instead of 3 years. The math on the kit is honestly insulting in your favor.
What is Ag+ Silver Ion technology and is it safe?
Silver ions are an antimicrobial agent — the same tech used in hospital wound dressings, athletic apparel, and Japanese premium toy-care lines. It binds to bacterial cell walls and stops them reproducing. Yes, it's safe for TPE and silicone toys. No, it does not stain or degrade the material. Yes, your roommate's chemistry degree would approve.
Can I use this on cheaper Amazon onaholes too?
Absolutely. The Ag+ Silver Ion formula is compatible with all TPE and silicone onaholes — Magic Eyes, Tomax, Tenga, Oo-Umai, even your $40 cone-shaped regret. Honestly, if you're going to keep buying cheap ones, this kit extends each one from "3 months" to "8–10 months." Same math, different starting point.
How often should I use the full 3-step cycle?
Foam wash + drying stick after every session. Ag+ powder once a week if you use her daily, or after every 2–3 sessions if you rotate. The powder is the preservation step — you don't need it after every use, but skipping it for a month is when TPE starts to get sticky.
How is this different from the Squirt Blaster (OH-OT-100)?
Squirt Blaster is the foam cleaner alone — $19.99, 1 component, post-session rinse only. The 3-in-1 Assassin Edition (this page) adds the drying stick and the Ag+ Silver Ion powder — the two steps that actually extend lifespan. Squirt Blaster is "I'm cleaning her." The 3-in-1 is "I'm caring for her so she lasts 3 years." Different jobs.
Can I buy the components separately?
Yes, we stock them separately on ADP, and at full price the three components run about $75 together. The Assassin Edition crew is $39.99 because Oo-Umai bundles the maid-waifu key art and we pass the bundle discount through. Buying separately makes sense only if you already own two of the three. Otherwise the kit is the right call.
What does it smell like? Is the fragrance strong?
Faint and Japanese-style — think baby powder with a clean floral note. Not perfumed. Not sweet. Not "lavender candle." Designed to neutralize residual TPE smell without becoming its own thing. Most buyers say they barely notice it after dusting. If you're fragrance-sensitive, dust lightly — the Ag+ does the antimicrobial work whether you can smell it or not.
Why "Assassin Edition"? Is the kit different from the other Oo-Umai cleaner sets?
Same Oo-Umai 3-in-1 formula, different cover art. The "Assassin Edition" is the maid-waifu key art variant — one of Oo-Umai's character series for the Undercover Crew line. Other editions exist with different waifus. The cleaner, the drying stick, and the Ag+ powder are identical across editions. You're picking your art, not your chemistry.
How discreet is the shipping?
Very. Plain brown or black outer box, no anime art, no brand markings, customs form on international orders reads "household goods" or similar generic descriptor. The Oo-Umai maid-waifu art is inside the outer box. We've been shipping this stuff to people who live with parents / roommates / partners since 2008. We are good at this.
When does it arrive?
Handling 1–2 business days before it leaves the warehouse. Standard shipping 7–14 days to the US and most countries. Express shipping 7 days or less. Tracking link by email; the carrier label does not say what's inside.
Can I return it if I just… don't like it?
Yes. 100-day no-questions guarantee, opened or unopened. Email support, plain-box return label, refund processed when it arrives back. Most shops won't return opened adult-care products. ADP does, because the alternative — you stuck with a kit you hate — isn't how we want to run this business. We've been doing this since 2008. The math works out.
