Masturbator discontinued
by Toy's heart

Tiny, suckling wonder from Nippon.

For an economy toy, Kozaru is a wonderful sleeve. Starts out tight and shallow, ends up slightly looser and open at both ends. I really enjoyed the addition of lubricant and the sample provided was very well paired with the toy it came with. Kozaru is a wonderful way to have some private time with your penis. I recommend it to anybody wanting a nice change from their hand.
Kozaru is small and light, very soft, and a joy to the johnson.
Kozaru looks like it won't last more than a few sessions, but time will tell.

useful review
Kozaru surprised me several times, once being when I first received the toy because I had not seen a Japanese sex toy and I find that the United States as well as Germany each has their own style of packaging that sets each country apart from the others. Japan was no different, and I was delighted to see how much thought went into the presentation of "Kozaru." Of course, being from Japan, Kozaru also featured a very, VERY well-endowed anime girl on the cover with a very anxious look in her eyes. Judging by her skirt, I would say that she was portraying a "school girl."

All over the box were happy, brightly-coloured kanji trying desperately to get my eyes' attention. I sadly have no idea what the kanji says, but I know that I got excited just seeing how it was presented. On the back of the box was a small section with the word "SPEC," which detailed in English the toy's size, weight, and material. I also saw a picture of the toy detailing the overall dimensions as well.

I also noticed a few warnings on the bottom and side that were foreign to me. Let's hope I don't do any of that forbidden stuff.

Upon opening the box, I found an unexpected gift: LUBRICANT! I was worried that I would need to go to the store and purchase some, because no penis deserves to fuck a sex sleeve without lubricant; I wouldn't wish that upon anybody, least of all myself. Thanks, ToysHeart! I also found the actual toy wrapped up in a plastic sleeve, looking cute, tiny, and VERY tight. I tried to make sense of the lubricant sample vial's text, realized I don't understand Japanese, and decided to put my faith in Japanese engineering.

Kozaru is crystal clear, made of elastomer, and is open at only one end. It is shorter than the average cock by at least 3", and at first glance looks to be engineered for the top two-thirds of a man's manhood. The toy has a delicate, almost fragile, feel to it, but can take a lot of twisting and stretching.
How does one actually use this toy, how do I fit this big dick into such a tiny slippery hole? Kozaru is small. The opening is no larger than a Bic pen is around, and if I lube myself up first, I might lose control of this tiny thing and watch it shoot off the end of my johnson and fly across the room. I decided that my best bet was to manually pour lubricant into Kozaru first, lube up my dick, and keep my thrusting hand as dry as possible, as dry elastomer is very clingy to dry skin. I had a hell of a time getting myself inside at first because Kozaru is very small and squishy. I tried once, slid across the opening, tried again, and met with a similar end, but on my third try (as well as with some fancy minimal contact dick holding), I managed to get inside.

Kozaru is a wonderful toy, it is really stretchy and nicely ribbed in such a way that makes my dick's head yearn for lots of fast stroking. Sadly, twisting is next to impossible because kozaru refused to twist on account of all the magnificent pressure it surrounded my pecker in. Kozaru felt best when I shoved myself inside as deeply as possible and stroked very little, almost polishing the tip (which was plainly visible poking out of the top through Kozaru's crystalline material). Kozaru is also silent because of its single entrance design.

I went at it for a bit, realized that if I didn't slow down, Kozaru was going to get me there sooner than I would have liked. Doesn't it know I need information and data for my review? I think it did, because I took my eye off it for a moment to look at some "supplemental stimulation" and noticed a unique feeling, Kozaru tore right through the top. "Oh no!" I thought, and kept at it, expecting the toy to rip right down the seams at any moment.

It didn't, though.

In fact, Kozaru surprised me for a final time when I discovered that the toy is actually better torn. And the tear itself is not bad, in fact the tear was more like three flaps sealing the entrance unless pressure was applied to them.

It should be noted that Kozaru is so tight that it can happily grab on to the base of a hard dick and sit like a really fat ring. This allowed me to have more control over motion as well as insert more lubricant into the toy (I needed four small globules during my twenty minute session).
Follow-up commentary
This toy isn't going to last very long. I have a feeling I'm going to fuck it apart within a month.

    From what I've seen, a lot of Japanese masturbation sleeves are small like this. Even the openings of Tenga holes look tiny in comparison to, say, the Fleshlight. Whether or not this is a good thing depends on ones anatomy I suppose. Good review.
