Plyo Boxes are especially helpful in developing agility and cardiovascular endurance.  Ours are US made, CNC Machined, just like our rings.  They're made with Baltic Birch plywood - not the stuff you find at the local hardware store.  Strong and dependable - just like you.  The edges are rounded over just in case your shin meets up with them [not that we've ever had that happen ;D]

We think we've got some of the best prices on the highest quality boxes on the market.  Wanna save even more?  Choose the unassembled 20x24x30...it goes together easily and saves you a bunch on shipping.
