Casper is my favorite dildo. It can be safely used vaginally or anally, thanks to the flared base. It's perfect for temperature play. It has just the right curve to stimulate the G-spot or prostate. I especially like Casper's realistic texture - the hard ridge right beneath the head is to die for! It's also a great idea to use a powerful bullet on the glass, so you can enjoy some nice vibration.

Borosilicate glass is one of the safest materials for sex toys as it is nonporous and durable — probably my favorite. Glass feels slightly cool, but it quickly warms up to body temperature when being used internally. It's amazing to feel exactly how warm it is once you pull it back out! If cold temperature play is your thing, you can chill Casper in the fridge, and go to town.

Casper was my first, and so far, my only realistic glass dildo. I love the ridge at the head, and the texture down the shaft is lovely.

Casper has 7 inches of insertable length and a diameter of 1 1/4 inches. The width is right on the edge of being large for me, but that's right where I like it. The curved shaft feels nice and helps position the head to stimulate my G-spot, though I don't use Casper for that in particular. Also, its gentle curve will not cause any discomfort when I use the toy anally, and the wide, flared base prevents the dildo from over insertion. The texture feels great. The kicker here is the weight; Casper weighs a full pound. I like some heft in my dildos, but I imagine this might be too much for some users. It's also not exactly the most travel-friendly piece.

I love Casper ... like, a lot. I love how warm the piece gets, and I love how the weight feels when I use it vaginally. My favorite part of this toy is how great it is when used with vibration. I especially like to use the Hitachi Wand on my clitoris and let it vibrate Casper at the same time.

Glass is compatible with any kind of lubricant you'd like to use. When you're done with the dildo, it's very easy to clean. You can wash it with soap and water and rinse it thoroughly, of course. You can boil it on the stovetop for some extra sanitation. There's also the option of just sticking it on the top rack of your dishwasher and letting it get clean that way. Although it might not need it, I like to give the dildo an extra rinse when the cycle is done.

Casper arrived in a velvet bag; I store it in there and put it in a drawer with soft items only. Before each use, I check for any chips or cracks in the glass. Because of the weight, size, and material, Casper can be a little more tedious to store properly than other toys.
