I have one glass butt plug & 4 glass dildos. They are more sanitary than traditional toys made from plastics & the ability to heat/cool them adds a another dimension to play. For travel, I have padded velvet bags I pack them in. Then, I wrap them inside of a towel. No breakage issues so far & I put them in checked luggage when flying.
I love glass toys too, I just have one but intend to purchase more. Glass can be sanitized, which is a big plus. Also, the smooth texture with lube is delightful!
After reading this thread I went out and bought 2 more glass toys. I love the idea of making them hot or cold. It reminds me of my first orgasm. I positioned myself under the running water in the tub and switched back and forth from warm water to cool water.
