No picture can really do these glasses justice. They have nothing aesthetic in common with any other double-walled cup I've ever seen--elegant, minimalist, super clear and light as a feather. They really keep stuff cold (or hot, as the case may be). They're even dishwasher safe. However, they are remarkably fragile. I accidentally rapped a spoon on the lip of one and within half an hour, the little crack had spread and the glass was in fragments. But if you're careful with them and keep them away from kids, animals, and, apparently, me, they will serve you well.
