These black plastic headbands are designed to be used in crafting projects. 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 an child from about age 4 through adults.
They measure 1-3/8'' (35mm) at it's widest point on the top and tapers to the ends. Each headband is approximately 15'' from end to end. There is also a slight, barely noticeable ridge in the middle of the headband showing the center point.
