MIU 4-Piece Silicone Baking Mats set includes two half-sheet size mats measuring 16.5" x 11.6" and two toaster oven size mats measuring 11.6" x 8.1". Made from FDA-approved food grade silicone, these mats provide a nonstick surface ideal for baking cookies, pastries, roasting vegetables, and kneading dough. They deliver consistent, even heat distribution across the baking surface.
The mats are oven, microwave, and freezer safe with an operating temperature range of -40°F to 450°F (-40°C to 232°C). Each mat features printed measurement markings in inches and centimeters, as well as circle guides for uniform cookie sizing. Clean with soap and water, wipe dry, and store flat or rolled. Do not use scouring pads or cut on the mats to avoid damage.
