These BISTRO mixing bowls are great for meal preparation. They feature an extra layer of rubber on the handle and bottom surface for a no-slip grip. The majority of new mixing bowls on the market are made of melamine, but the BISTRO mixing bowls are made of recyclable, BPA free plastic with an added rubber layer for a no-slip grip. The small rubber dots strategically placed around the bowls surface are designed for added stability at any position while mixing. The mixing bowls come in different eye-catching colors.
