FLEXIFORM MAIZES FORMA 25CM, SILIKONS, Lurch   Muffin pans and leba pans are special kitchen containers used for baking muffins. They can be made of metal, silicone or plastic and come in a variety of sizes and shapes, usually round or rectangular. Muffin tins usually have a non-stick coating or silicone surface, which makes the finished muffins easier to remove and easier to clean after use. These pans allow the muffins to bake evenly and maintain their shape during cooking.
