Hair chalks from BigOtters are great! This set contains 6 different colors of hair chalks. I love the colors that came in. Vibrant Pink, purple, blue,yellow, green and blue~ Easy to apply onto hair to get the desired color of the hair. These are temporary hair dye chalk and can be washed/cleaned easily with water and shampoo. Great for attending parties, dress up, Halloween, or just want to add colors onto the hair~ Have fun and be creative!!!
