Yeah… that’ll show us…

It looks like OP is just copy-pasting from the source title (which sounds like an Amazon listing). OP, it would be cool if you could… not use those titles :)

Yes, “Nitrile Rubber”, not to be confused with natural/latex rubber, butyl rubber, etc.

Nitrile is the standard material for latex-free exam gloves.

I’m a fan of nitrile. Silicone is easy to fit because it tends to have a lot of stretch, but I find it also tends to pinch a bit because of that stretch. Nitrile is still relatively soft and has some stretch, but quite a bit less than silicone. Less stretch means you need to buy the right size, but they are inexpensive and you can get multipacks to figure out what size you need.

I’m curious what you found. I only found one - the alien stroker - it looks like it could be 100% silicone, but noticeably the description doesn’t clarify whether it is a blend or not. And there are 0 reviews.

FYI, if it is 100% silicone, you can boil it to clean it. If it is a blend (or not silicone at all), boiling should fuck it up.

I have looked for the same in the past but didn’t buy because after researching it didn’t sound like a silicone stroker would work well. From what I saw, silicone is just not stretchy/soft enough. Because of this a 100% silicone product is not going work well unless you can get one that is the exact right size for your dick.

I didn’t look further to see if I could find anyone making silicone strokers in a variety of diameters - I suppose that could be a solution.

If you do find something that claims to be soft, stretchy, and silicone, you should do some digging to see if the mfg is trustworthy.

All that said, if anyone has a 100% silicone stroker that does work, I’d love to hear from them!
