These bracelets are very small. I have a fairly slender wrist & hand, as well as my mother who I bought another one for. Her hands & wrists are very petite. Neither of us could get these over our hands. When I took them into a local jewelry store, they were the same size as their little girl bracelets. Sure enough, when I arrived back from being told there would be no way to extend them without it costing more than these are worth, I compared them to a bracelet my little niece wears, and it is the same size. When I compared it to bracelets I buy in department & jewelry stores, they were considerably smaller. Unless your hand and wrist are the size of a child's, don't bother wasting your money. I hope Birchbox will refund my $36.
