Wasn't sure about glass at first but the weight feels surprisingly substantial and smooth in hand. The two different shapes actually matter, one is gentler while the other gives more of a curve, so there's real variety to switch between.

The two different shapes in this set are genuinely useful depending on my mood, and the double-ended design gives plenty of options. Warmer than I expected once rinsed in hot water, though I do wish the set came with a storage pouch.

The double-ended design gives you two different shapes to play with, which is more versatile than I expected. Glass warms up fast with a little water, though you'll definitely need lube since there's no give at all.
