Thanks, guys. The necklace was fun and FAST to make. When I initially saw the kit, I thought I'd make one for EVERYONE for gifts ... until I saw the price of the clasp. Then I decided it was just for me!
The kit is just the magnetic clasp and instructions on how to glue it into the clasp. I think it was about $40.
I've looked around for other magnetic clasps but haven't had any luck.
