This large, silicone pastry mat provides a hygienic, non-slip surface for preparing all kinds of pastry and icing. It has a handy rolling size guide printed clearly on its surface and, unlike other pastry mats, an integrated, lockable strap that keeps the mat securely and neatly rolled when stored. Pastry making has never been so easy or fun with the Roll-Up Pastry Mat. Dishwasher safe. By Joseph masters of form and function.
