The linear dimensions of our sheets are nominal and they have a tolerance of +-1/8"" in each direction (length and width). Therefore the dimensions you request will be within the tolerance stated Available in multiple sizes and thicknesses. Made of a high density polyethylene specially formulated for quality cutting boards. The surface finish insures long product life and will reduce the dulling of knives. High density polyethylene outlasts (up to three times longer) functionally competitive materials and is considered the strongest and lightest of all cutting board materials. This is raw cutting board material and will have saw cut edges, see pictures.
