There are primarily two kinds of bracelets: worked or memory wire.
Worked Bracelets are made without clasps. The length indicated is finished without clasp.
When you order it, you can ask for it to be lengthened. Some bracelets made WRAP style can be shortened.
Remember wrapping a SLINKY around your wrist and wishing you could keep beads on it?
That's Memory Wire. It just wraps around your wrist...or ankle...and it retains it's shape.
It fits everyone. Kids can grow into them. No clasp, no worries. Just wrap.
