Terpgurl... they are just a plastic wristband. Depending on how your guests have booked, the color is different. VIP Members have black bands, members have silver, honeymooners have pink, kids have purple, and everyone else has yellow. They are probably about half an inch wide. They put them on pretty snug, so you can't slide them off. We also had wrist corsages for the mothers, to cover their bracelets.
