These glasses are super cute, BUT, they don't last! We bought them for use in our pediatric dental office. We give them to the kids, and then take them at the end of the appointment, there really isn't opportunity for them to mess them up. I bought one set, and a couple of them broke within a week. I gave it the benefit of the doubt that maybe kids had been too rough with them, so I ordered a second bunch. Out of 12 we have 5 left, and we've only had them about a month. They just aren't durable See full review
