Very durable. Most of the stuff that I buy as “bori†still has that slightly green tint to it some more than others. Not this stuff. Since it’s actual “boriâ€, it has a higher melting point so if you’re working with just propane like me, it’s much harder to manipulate. It’s been working, just takes prob twice the time per piece. Durable and def good value for the money when they’re giving twelve for the same price the other guys are giving you ten. And they have 24â€ers for even less. Def gonna get some of them next time

The glass arrived broken. The equivalent of a stick or two. Even though it was absolutely worth every penny.

Perfect for what I needed it for! Thick glass and a great deal. Stock up instead of going to the store.
