Yay! I love glass! I've just started my toy collection. Textured glass seemed the most appealing to me so I bought the swirled G as my first toy ever, I swear it gets better and better everytime I use it. I want to try something with even more texture and I have my eye on this or the blue swirled dildo!
I've dropped my swirled g and nothing happened to it. I've also read numerous stories of glass toys being dropped on carpet, tile floor, etc, without breakage. Not to say that glass toys are indestructable, but they aren't as fragile as you may think.
I also think that there are a lot of glass toys you could possibly use as displays, or leave out in the open without anyone suspecting the true nature of the toy. Because they are glass, they do need to be stored properly, which is kind of an extra incentive to keep whatever you don't want seen in a safe place.
