The Anime Muscle Sleeve is a stretch-to-fit sleeve for either a vibrator or that special guy you have coming over tonight. It is used by stretching the sleeve over a penis or vibrator and you can cut it to the desired length for either. The best way to use the sleeve is with a little water based lube so it is easy to take off. Once on the sleeve has a very tight fit and a condom is not required, but that is up to the wearer.

This sleeve is made of latex free, phthalates free, hypo-allergenic TPR which is a polymer blend or compound that exhibits a thermoplastic character (according to the materials page here on EF).

The sleeve is blue in color with a ribbed outside surface and smooth inside. Provides added girth, support for him, and sensual thrills for both him/her. Trim-to-fit feature for exact sizing on a penis or vibrator. According to the box it's (5½" X 1¼") with a net-weight of 1 oz.

To me, this didn't perform well at all. While being simple, straightforward, and easy to use. The tightness made it very uncomfortable to keep on for too long. I also don't think that this toy would hold up well over time.

For storage, I recommend keeping this toy in a plastic bag so it doesn't pick up lint and hair. Keeping it away from other toy materials is also a good idea because I'm not sure what might happen to TPR if it comes into contact with other materials.

This sleeve can be cleaned by washing it with antibacterial soap and water. It is a little hard to turn inside out for cleaning though. It is also important to only use water based lubes with this sleeve because others may damage the material.

It comes in a bright yellowish-orange box that has been illustrated in Japanese.
