These bracelets should only be advertised for adults as the bracelets for children would be too big. The bracelets fit my husband's wrist well, but they are loose on mine, so obviously they would be very large for children. We bought them for parties for children aged 8-13. I'm sure they will still like them even when they grow up. I just want them to be really suitable for children. They are very well made so we're keeping them even though they're big.
