Our oversized pure white bow is made from soft, 100% cotton. Each bow measures approximately 4" across and can be attached to a nylon headband or alligator clip. Moms love our one-size nylon headbands because they can't be outgrown and don't leave marks/indentations from being worn. They are extremely soft and stretchy and fit newborns through adults. The alligator clips are can be removed from the bow and reversed so they can be worn on either side of the head.
