This is an A4 size Tuile Stencil for making Tuile biscuits or wafers.  They can also be used for chocolate making too.

They are made from a really tough food grade plastic.  The outer dimensions are A4 in size ie. 297mm x 210mm.  The thickness of the stencil is 1mm which is perfect for Tuile making.

They are not suitable to be put into the oven.  Making Tuiles requires the stencil to be removed before placing into the oven.
