It may look simple, but there's a lot to like about this masturbation sleeve. Its odorless material, subtle internal texture, suction control, and ability to maintain heat make this a very nice toy for beginners and 'stroker pros' alike.


Safe material. Unique ability to generate and hold heat. Suction control.



Best use:

The Si-x Type N from Toy's Heart is hand held penis sleeve that's not only easy to use, but easy to take care of too. Its stretchy material is made to accommodate men of most sizes and will add some unique sensations to your self-love sessions. The thick design also makes it very easy for a partner to grip and control, so it can be used as a couple's toy as well.
  • Material / Texture:

    The Si-x is made of Japanese medical grade thermoplastic elastomer called "Fine Cross", which contains no phthalates and is considered completely non-toxic. In spite of its rubber-like appearance, Fine Cross doesn't contain latex either nor does it have any scent, so people with allergies don't have to worry.

    If you've ever tried a Fleshlight, then imagine a material that is just a bit firmer and a lot less delicate feeling. If not, then the feel is best described as being more spongy than rubbery, and having a soft surface with just a little bit of drag to it both inside and out.

    During use the material provides a slight amount of pleasant friction, but never rubs you the wrong way (assuming you use lube!).

    Material safety
    Safety features:
    Hypo-allergenic / Latex free / Phthalates free
    Ribbed / Velvety
  • Shape / Design / Size / Fit:

    The design is rather "hand friendly" meaning that it's neither too big nor too small to comfortably hold. Both ends bulge slightly larger than the center, and there are alternating smooth and pebbled textures on the outside that help you maintain your grip.

    The outside of the toy is around 6" long, but it's fairly thick and closed-ended so there's maybe an inch less than that inside. All the same, because the material stretches so well, it would comfortably accommodate men up to 9" in length and 2" in girth. Smaller than average men should be able to enjoy the Si-x sleeve too, because the opening is only 1/2" across. The entrance is fairly non-realistic, and the hole is inset so it's easier to penetrate.

    The inner texture shown on the box is not an accurate representation of what's inside the sleeve. There are five chambers of varying widths and lengths, but only the first two have the up-and-down striations as pictured. The next two have bumps, and the final chamber is smooth.

    Fits up to:
    Vaginal depth:
    5 1/2"
    8 oz
  • Functions / Performance / Controls:

    This is no "basic" masturbation sleeve when it comes to performance. To begin with, if you knead it in your hand for a few minutes before use, the material becomes warmer inside and out and tends to stay that way during use. That does give it a more realistic feel right off, without having to pre-soak it or anything.

    Using lubricant with the Si-x Type N is almost a necessity to ensure that there isn't too much friction, but it doesn't take much to get started and the toy holds the lube inside very well.

    When you first start to enter the sleeve, squeezing firmly on the closed end expels air from the last chamber to create suction, which it maintains pretty well until you completely remove yourself from the sleeve. It's best to squeeze a little out to begin with and then a little more during use until you find the suction level that you like, because if you squeeze all the air out the suction is very intense and some men might not find it pleasant. Gripping the center of the toy tighter obviously increases the overall tightness of the sleeve too.

    You can feel all of the textures and the raised areas between the chambers during use, but not in a specifically defined way. It's more of an overall pleasant sensation that wouldn't be too intense even for a beginner to masturbation sleeves.

    As with most closed-end sleeves, the Si-x does make a quiet slurping noise during use, which is something to consider if you're trying to have a quick session with someone else sleeping in the same room. Squeezing air out of the end chamber during use will make the occasional rude sound all of its own, and that tends to be a little bit louder.

    Special Features:
    • Lubricant included
    • Realistic design
    • Super stretchy
  • Care and Maintenance:

    The best way to clean this toy is to turn it inside out and wash it with antibacterial soap and water, which is fairly easy and something that you can do without getting the impression that you're stressing the material any. After you're done, you can towel dry it or just leave it sitting out to air dry. Any fuzz that it may pick up from the towel can be easily brushed away after the toy is dry.

    It's safe to use any water based lubricant with it, and you should store it away from other sex toys to avoid possible material interactions.

  • Packaging:

    The Si-x Type N comes in a medium-weight white cardboard box, wrapped in clear cellophane. The toy is also wrapped in cellophane-type material and feels like it's coated in some sort of light lubricant when you first unwrap it. This washes away very easily though and leaves no residue.

    There aren't any instructions for care or usage included, and most of the writing on the box is in Japanese. What English there is doesn't give much information, but it does assure you that the toy can give you "Olgazms".

  • Experience:

    Alan says:
    It gave me Olgazms, just like they said.
    Ok, seriously, I really did enjoy the sleeve and it's another one that I wouldn't hesitate to suggest to others. It didn't feel like the "real thing" (what does?), but I don't have a single complaint about it. All sleeves feel unique, but when you add the heat thing and the suction and all it's just a well-rounded experience for any guy.

    Michele says:
    The more I use these little caseless sleeves on him, the more I like them. This one was even better than the last one we tried though, simply because it was so easy to hold onto. Yes, even when you get lube or soap on it, it's still easy. Another thing I like is that it's not really sticky like a lot of other sleeves we've used. It's surface is a little odd to hold, but doesn't make me feel like I need to wash my hands afterward or anything.
