The loud "pop" the flag makes when it's pulled off is what makes the Sonic Flag-A-Tag different. No more confusion about when a player is "down". The heavy duty belt has 15" vinyl flags that are attached by a socket system, which lets them swivel, keeping them away from the body during play. Each set includes 12 belts & 24 flags of specified color. Available in 2 sizes: fits up to 42" waist or up to 52" waist.
