Pura Vida Jewelry Bracelets - 100% Waterproof and Handmade w/Coated Charm, Adjustable Band

Q: How do you adjust the size?

I found that the central piece, that one would pull the two strings tighter through, was hard and waxy. I could not pull the strings to make the bracelet tighter. If I could then they would be rather long. If you cut them then they will ravel. Confusing.
