What a hit! We let the kids decorate these with sticky gemstones for a birthday and they were perfect. The front and sides are nice and flat so it made it really easy for their little fingers to find places to stick the gems. We had 2-8 year olds and not a single pair of glasses broke - impressive! They do feel a bit lighter weight than the ones you usually get with promos or see sold individually in the store, but this wasn't a con for us, I just thought I would point it out. Would definitely recommend for parties.
