There are two kinds of kitchen drawers. In one, the pans each have their own space. In the other, they're stacked inside each other, slowly scratching each other's surfaces. These protectors are for the second kind.
Two round protectors in black silicone from Demeyere, 40 cm in diameter, to place between your pans when you stack them. The silicone is soft and moulds itself to the pan, so it sits nicely even in smaller sizes. Don't use them as trivets for hot pans.
