I love the adult masks, have re-ordered many times, so have bought over 300. However, they're too big for my 12 y.o (4'11") daughter, so I thought I'd order the Kids mask for her. They are very small, I'd recommend for under age 10. I'm very surprised other reviews said they fit small adults. I didn't realize a few cm makes such a big difference. Too bad the lowest quantity option was 10. I bought the mixed bag (50 adults/25 kids) because it was better value.
