Grace Kamila 4 The size is perfect to work with bread dough or any baking required. Before this I used any surface available and it could be sticky and hard to clean. But this sheet is much easier to rinse or wiped with damp cloth. However, if you prefer to rinse it under running water in the sink like I do, it is a bit difficult because of the size.Other than that, it works fine so far. Also heat retention is very good.
