ONE SIZE FIT ALL - The headband in this boxing reflex ball set is made from elastic string and nylon, plus the hook & loop closure design. It fits for head circumference from 16 1/2 inches to 27 1/2 inches and works for anyone
TWO DIFFICULTY LEVELS - The Novices ball is slightly softer, and the string connect to it is much thinner to help beginners easy to learn, whereas the bungee on the Veterans ball has a lot more spring, making it moves faster and less predictably
THREE VERSIONS - We have three versions, Black/Red, Pink/Red, and Yellow/Red. They are all packed in a lovely gradient color lid and base box. The black, pink, and yellow balls are soft and of low speed, as they are for beginners
AN ADDICTIVE WORKOUT - Just search the keywords "addictive" in the review section and you will know it. Here is a example: "The time flys by and you don't realize how much you've been training"
A FUNNY GIFT - In the beginning, watching your loved ones working hard as a cat but NOT being able to hit the ball is quite funny. And then it becomes an entertaining competition once there's someone get the hang of it
