"These were a huge hit with the kids at my daughter's Harry Potter birthday party. Two of the girls even wore them to school the next day during reading. Love the funky glass lenses--that don't negatively affect vision. These are quite small for most of the 11 year olds at the party. Only ~3 wore them the whole time, the other 8 just had them on for pictures--mainly because they didn't fit well enough. Great purchase--especially with the bulk option (instead of individual pieces)."
