The audio work that needs hardware costs ¥770. The hardware costs US$14.

There is a work in the catalogue here built entirely around owning a prostate massager. It says so in its own title. The obvious follow-up question, if you do not own one, is what that actually costs you before the audio makes any sense.

Fourteen dollars, as it turns out. Which is less than the shipping.

The shop that pays best does not sell these

Worth knowing before you go looking, because it cost me an hour.

I searched the two big English-facing Japanese shops for prostate gear. One of them, otonaJP, is excellent for masturbators and has a proper English catalogue with published weights and dimensions. Search it for "prostate" and you get one result, and that result is not a prostate toy. Search "enemagra", the Japanese generic term, and you get nothing at all.

Kanojo Toys has a category literally called Anal & Prostate Toys with 492 products in it.

So if you are shopping this specific corner from outside Japan, that is where the stock is. I am not going to pretend otherwise to keep things tidy.

What ¥770 of audio actually commits you to

This is the cheap, simple end. No motor, no app, no battery. TPE, a handle you hold, and a knob on the end of the handle that sits against the perineum while the rest is inserted.

The numbers that matter are the last two rows. 32mm maximum diameter and 116mm insertable. Write those down, because they are the entire decision, and half the listings in this category do not publish them.

For reference against the rest of the shelf: this sits at the beginner-to-middle end on diameter. The motorised things in the same category run from US$26 to US$51 and are mostly wider. If the audio work is the reason you are buying, wider is not better. The work is a sixty-ish minute continuous sequence and comfort over time beats intensity.

The honest maths

The work is ¥770 at list, and it discounts often. Call it US$5.

The hardware is US$14, and international shipping from Japan is charged by weight rather than order value, so a single 88g item is close to the cheapest thing you can put in a box. It still will not be free, and the shipping cost is never printed anywhere until the basket, which is a separate irritation.

So the real entry price for that audio work is somewhere around US$20 to US$35 all in, not the ¥770 on the product page. That is still cheap for something you can use indefinitely, but it is four to seven times what the listing implies, and nobody says so.

If that number is the blocker, there is another work from the same circle that needs no equipment at all.

What I am not telling you

How it feels. I have not used it and I am not going to write as though I had.

This listing also has no customer reviews and no rating at all, which I would normally treat as a warning. Here I think it is mostly a function of the shop rather than the product, since the entire category is thinly reviewed. Either way: there is no crowd to check against on this one, so buy it on the specifications or not at all.

Two numbers, then decide: 32mm and 116mm. If those are wrong for you, nothing else on the page matters.
