There are 6 vibrant colours: pink, red, yellow, orange, blue and green. The straps are soft, breathable and lightweight. There are 2 of each colour so you can wear a matching pair. The bright colours will get your child's attention if you are using them for hand eye coordination learning. These colours would also go with any birthday party decor theme. To keep them bright and vibrant, the straps can be washed with dish soap and the bells can be wiped clean with a cloth.
