About the headband: 
 
Each crochet unicorn horn headband is made with 100% cotton yarn and features a white unicorn horn accented with pink ribbing, white ears with pink inner-ears and a garden of wildflowers in shades of pink, teal, white, yellow, and lilac. The headband is made of sturdy metal, yet it bends to fit many different shaped heads. It is covered in soft satin for comfort and a silicone “grippy strip” to keep the headband from slipping around.
