A10 Piston SA × “Mada Namae ga Arimasen”: The Ultimate Combo
Lots of reviews on NLS (the official Japanese online store for RENDS/VORZE) said that putting the “Mada Namae ga Arimasen” onahole into the A10 Piston SA makes it feel devastatingly good, so I tried it myself.
“Mada Namae ga Arimasen” (literally “No Name Yet”) was the No. 1 most popular onahole on NLS, a big Japanese adult store, when I wrote this in October 2022.
For me it became a must-have — to the point that I can’t go back to the official sleeve that comes with the machine.
The reason: the stroke is longer, so there’s more up-and-down friction than with the official sleeve, and that feels great.
The stimulation gets stronger.
With the official sleeve, the front cover of the A10 Piston SA also kept popping open and shut, and that problem went away too.
If you feel “the stimulation just isn’t enough for me to finish,” you really should buy one.

Does Mada Namae ga Arimasen Even Fit the A10 Piston SA?
You might be worried about whether the “Mada Namae ga Arimasen” onahole will even fit.
It fits with no problem.
That’s because it’s exactly the right size for the sleeve case.
Normally you have to line up the official sleeve’s “six holes” with the case, but with Mada Namae ga Arimasen you don’t need to.
It’s a snug fit, and friction against the case keeps it from slipping, so you can buy it with confidence (that’s what I found with mine in October 2022).
At first I thought, “If I put Mada Namae ga Arimasen into the A10 Piston SA, won’t there be no room left to insert my penis?” — but it was fine.
4 Things I Noticed Pairing the A10 Piston SA with Mada Namae ga Arimasen
[1] The A10 Piston SA’s front cover stopped popping open
I wish I’d bought it sooner.
Back when I used the official sleeve that came with the A10 Piston SA, the front cover kept popping open and shut, and I couldn’t concentrate.
Every time, I dealt with it by adding more lube or attaching the Den-Ona Holder (NLS’s own mount for electric masturbators; as of September 2026 it’s ¥2,156 (about US$14) and still lists the A10 Piston SA as compatible, but NLS showed its restock date as undecided).
But with Mada Namae ga Arimasen, nothing presses against the cover, so it no longer pops off — much more comfortable.
Maybe because it grips so tightly inside, it lasts all the way to the finish even with less lube.
So I could stay lost in the VR video without my focus breaking.
[2] The stimulation got stronger
With the official sleeve, the white plastic part in the photo above is held in place, so your penis doesn’t get much stimulation.
Only the part near the opening stretches and does the work.
Mada Namae ga Arimasen, on the other hand, moves the full distance the A10 Piston SA strokes.
That means it works your whole penis, so it feels much closer to the real thing.
[3] I didn’t need to worry about getting caught in the machine
I was worried: “Could my penis get caught in the A10 Piston SA’s machinery?” — but that was no problem.
I never felt it was dangerous.
Even with a VR headset on, I could relax and enjoy it.
[4] Cleanup got easier
Mada Namae ga Arimasen is more compact than the official A10 Piston SA sleeve, so it’s easier to handle.
That makes the annoying cleanup easier, too.
A diatomite drying stick fits inside as well.
Because it grips so tightly, I feel the diatomite stick soaks up more of the water.
How to Put Mada Namae ga Arimasen into the A10 Piston SA
Just open the case and drop Mada Namae ga Arimasen in.
You don’t have to worry much about which way it faces.
Whatever the position, you can still insert your penis.
Once it’s in, attach the case to the A10 Piston SA.
You can use it without the front cover, but it’s better to put it on so you’re less likely to get caught in the machine.
Mada Namae ga Arimasen comes with a single-use packet of lube, so use it ↓
Before putting Mada Namae ga Arimasen into the A10 Piston SA, squeeze the lube all the way inside — that way it won’t spill. I recommend it.
If you don’t use plenty of lube, the A10 Piston SA gets strained and may make strange motor noises, so be careful.
This isn’t normal use, and it can break the machine, so always use lots of lube.
Personally, I found RENDS’s own lotion easier to use because it’s thicker.

How I Recommend Storing Mada Namae ga Arimasen
Mada Namae ga Arimasen doesn’t come with a storage case.
It just arrives in a small cardboard box.
So my recommended way to store it is to simply leave it set in the A10 Piston SA.
Then it’s ready to go the next time, too.
How Does Mada Namae ga Arimasen Arrive?
It was double-packed, in a black bag and a small box, so it’s unlikely anyone will notice what it is.
Open the bag, and you can put it straight into the A10 Piston SA and use it.
