The silicone used in the Tantus Stroker XL is a opaque, white colored material that is definitely firm, but has more give to it than most of their toys. This does not resemble flesh in any way, and would probably be best suited for the experienced sleeve user because of the firm inner ribs. It's open end design does not create suction, but simply creates pleasure in the motion.
This toy is a definite improvement over the first model. In my experience, the first model was too small for my partner to even penetrate. He was able to fit himself into the Stroker with a lot of water based lubricant, provided it was still a very tight fit. Most men should be able to use this, except those on higher end of circumference. The size is great for covering most of your shaft, and more length endowed men can easily avoid stroking the firm material over the sensitive head because of it's relatively short length of 5.5". The toy is a cylindrical shape and because of the material, if one would put it in, say a sock, it'd virtually disappear in a drawer or suitcase.
The Stroker XL is made of 100% platinum grade silicone from Tantus. Its care is relatively easy compared to the intricate care some other sleeves demand. As it is silicone, water based lubricant is definitely preferred, though a spot test may prove a silicone lubricant can be used. This sleeve can be entirely sanitized by either boiling it, running it through a dishwasher (top rack, no soap), or dipping it in a tub of 10% bleach solution (rinse after!). If you are not planning on sharing it, the Stroker XL also cleans up very nicely with some soap and water. The Stroker should be stored in a bag of some sort to protect it from contacting other silicone and to help keep it clean.
The packaging of this toy has also been updated since the original Stroker. It came in a simple environmentally friendly plastic bag with a cardboard tag stapled to the top. I initially didn't care for it because it isn't appealing for gift giving, but it is definitely the more green way to package toys.
