The Plyo-Safe™ line of plyo-boxes continues to revolutionize the plyometric industry offering the ultimate combination of durability, stability, and safety. With an extra-large landing surface of 30" x 36", athletes' fears of missing the box are eliminated. Made with a 100% foam core that will not break down, delaminate, or soften over time and a 21 oz. knife coated vinyl with built-in bacterial inhibitor. The handles on the 12", 18", and 24" allow for quick repositioning. Each box has three 2" strips of velcro to enable stacking and prevent the boxes from slipping apart during use. Available individually in 5 heights, as a set of 3, or a set of 5. The 24" and the sets are shipped freight. ***Only black & royal blue boxes are subject for return. All other colors are non-returnable.***
