This magnetic trivet can be criss-crossed under pots and small dishes or separated and placed in twos under large dishes and roasting pans. Thanks to be integrated magnets, the trivets follow the cooking pot as it is passed around the table. When not in use, the trivets fold up neatly to save kitchen-drawer space. The trivets are made of heat-resistant silicone for effective table top protection. Dishwasher-safe.
