I have gray hair so the black rubber band showed under the rhinestones. The solution for me was to cut off the black elastic and replace it with a light colored elastic band. Maybe DWC can make the rhinestone pieces with different color base bands for future purchases from other customers with lighter colored hair.
Just what I was looking for.
The rhinestones move and bend with the elastic, which is what I wanted for my son's destination wedding ponytail. Most I looked at were set at a certain circumference.
