This is a sweet little fun to wear bracelet! It is lighter weight, 5mm x 1.25mm sterling. You may want to buy the next larger size than you would normally take so that you can keep it squished down further. With the lighter weight silver, it makes it more secure.
If you are looking for a sturdier piece, check out the "Gabriella Cuff".
