These white plastic headbands are designed to be used in crafting projects. They have a semi-gloss finish that can be left exposed if you prefer. Each package contains 12 headbands. They are made of an ''unbreakable'' plastic, but keep in mind that anything will break if you try hard enough. They are a one-size-fits-all and will fit a child from about age 4 through adults. They measure 3/8'' (10mm) and do not taper. There are two rows of small teeth on the underside of the headband.
