They are super-slick with lube, have a great "weight" to them, can be cooled/heated in water if you like temperature play, are super-hygenic and easy to clean, look really cool, and will likely last a lifetime if you take care of them correctly. That help?
Not all of our toys are glass, but having a couple glass toys has definitely been a lot of fun.
They are awesome, I have recently been introduced and I have more ordered on the way. Temperature play is amazing, they are slick, firm, most are pieces of art work lol. And EF has a bunch for reasonable prices.
SSA Glass in particular has a huge selection of beautiful glass toys, most (maybe all?) of which are under $30 and are usually on sale. In a lot of cases the material alone makes them pretty discreet, and they are incomparably filling!
i was one of those people that didn't like glass, I didn't see the "nice feeling" everyone was talking about. But, since looking through the variety of toys that Eden carries, I think they are growing on me. I am looking into getting a few of them soon.
Honestly though, the artistic ones with the beautiful designs are the ones that have been appealing to me. I am looking at collecting some of them just to have a collection of great art pieces lol.
