Challenge teams to see how many they can stack while moving before the pile falls over, or see who stacks a certain number the fastest during a relay! Roto-molded plastic is durable yet lightweight for easy use and transport. Texture prevents slipping but adds a slight challenge. Each box is 12"L x 12"W x 2"H; 1 lb. Set includes 24 boxes, a VersaBag™ mesh storage bag, and activity instructions with unique ideas.
