Casper, made by Eden Toys, is made of Borosilicate glass which is also known as Pyrex glass, and it is a 10 on the safety scale. It is extremely smooth, so you can use it for vaginal and anal sex, and it is also nonporous, so it is easy to clean with antibacterial soap and water. You can pretty much clean it the way you'd clean any other sex toys, just be careful not to expose it to fast changes of extreme temperature. You can also you can use any type of lubricant.

It does have a flared base, which makes it easy to grip, and I imagine that would be useful for strap-on playtime.

If you want to cool it down, I suggest putting it in an ice water bath, or maybe even just sticking it in the fridge for a little bit. I only had it in the fridge for maybe 20 minutes and when I took it out, it made my hands super cold for a bit, so you don't need to go crazy and put it in the freezer unless you really want to. If you want to heat it up, I suggest putting it in a bowl of hot water and gradually increasing the temperature safely so that the glass doesn't crack.

One of the only things I was not amazed with was the price. But, even then, I think that the price of $25 or so was rather worth it for a quality item and I think it is definitely worth dropping $25 for. The other thing I had a small problem with was the packaging. I believe that if you order a glass item, it should probably be packaged a little more carefully, with maybe something other than just paper and one sheet of bubble wrap.

I originally bought Casper because I was looking for something realistic, but made of glass, and a bit larger than some of the other glass toys I eyed on Edenfantasys. When I found this product and read though some of the other reviews, I was very sure that this was the item for me.

Casper is the first glass toy I've bought so far, and I am very pleased with this product. It is obviously well made and of high quality and that immediately caught my attention.

When it arrived today, it was in a plain brown box, so it was very discreet. When I opened it, the toy was cushioned by brown paper, wrapped in bubble wrap and was inside this pretty ruby-red velvet pouch.

At first, I was a bit surprised it didn't come in a box of its own, and I was a bit worried that it might've been damaged, but it definitely is in top condition. When I took it out of the red case, I immediately noticed how smooth it felt in my hand, and how heavy it is.

I believe that it matches the size of most real cocks. The textured veins on the sides were quite noticeable and the head of it was able to be felt during use. I was very happy with this product.
