Thank you for viewing! This is a bag for rhythmic gymnastics balls. It's a drawstring type without a gusset. The color is rainbow. Black is used for the part where the string goes through. Since it uses stretch fabric, the ball slides very well and it's easy to take in and out. I took the photo with a string attached, but the string is not actually included, please be aware. I've lowered the price accordingly. Please choose your child's favorite string color. I am not a professional or a shop. Please refrain from purchasing if you are looking for perfection. Thank you very much (*^^*)
