The vegetable chopper is made from high-quality, food-grade, BPA-free plastic. Therefore, it is durable and able to withstand the powerful cutting movements of the 3 sharp stainless steel blades. The chopper container comes with a locking mechanism that holds it firmly in place, so you don't have to worry about any slippage during use. It also comes with a non-slip base to ensure it stays stable on any kitchen surface.
