Alphin Pans perforated Thin Crust pizza pans have an unfinished top edge that can cut dough, which allows you to roll out the dough over the pan with a rolling pin for fast, consistent results! The perforated TPP pizza pans contain 10mm holes that allow the bottom of the pizza to cook fast and provide a delicious golden crispy crust. The perforated base also allows finished pizzas to stay fresh longer by allowing moisture to escape.
