Well, this isn't quite true. Jelly and other potentially harmful materials are sold here and are very popular, so that logic is flawed.
However, glass is VERY safe. They're not made out of the kind of glass that your average drinking glass or something is made of which breaks easily. They're not hollow and they're made of solid, heavy glass that is not the type that shatters or splinters. It's not going to break during normal use. You have to drop them very hard on a very unyielding surface to break them and even then, it will usually just crack or break off a chunk and then you know to throw it away. You're supposed to check silicone toys routinely to make sure they don't have any scratches, tears, etc in the material and glass should be checked in a similar fashion for cracks or chips, which are unlikely if you don't drop them and store them in a way that prevents them from clinking around too much (padded pouch or a box that holds them). I think it's easier to damage silicone than glass, actually. I've seen a lot of posts about people being afraid a toy would break inside them but that's really not possible as long as you're using boroscilicate (pyrex, tempered) glass toys. They score a perfect 10 on Eden's safety scale. The only safety risks are bruising from rough thrusting (also equally possible with any other rigid material), and extremes of hot and cold due to improper heating or cooling of the toy for temperature play. But in general, glass toys are very durable and safe. Not to mention, compatible with any type of lube you might want to use and easy to clean and sanitizable! Boil it, bleach it, dishwasher, rubbing alcohol, whatever you like. So it's very safe to share between partners or orifices.
