These glasses were a waste of money. I've had them for roughly 2 months and 3 of the tall glasses have broken in the exact same way. The bottom of the glasses are not layered or thickened in any way, so the corners chip off. It is nearly invisible though so you only discover the glass is broken when you're pouring iced coffee into the glass and it's suddenly all over your counter. Wayfair charges for returns and I'm willing to bet they won't refund me in anyway. Don't waste your money. They are cute and look nice, but the quality is abysmal. I will eventually need to buy more glasses ELSEWHERE when the rest inevitably break. Good luck
