Review on ☕ Effortless Pour Espresso Cups Set by James Dominick

I got 4 of these, on first use 1 of them somehow ran espresso into the isolated/open area between the glass. I can't find a crack or break, but it's definitely there somewhere. I will resend / ask for a refund. The other 3 are fine so I think one of mine was just defective. I really like how easily they move in them with hot espresso. Because there are two separate pieces of glass, you can hold the cups even when the espresso is hot without burning your fingertips as the extra piece of glass creates insulation and distance between you and the hot liquid.
