PVC Board GIANT Checks 30"x60" ?'s firstname.lastname@example.org GIANT checks printed on 1/8" Smooth PVC are our original Big Checks. The 1/8" smooth PVC plastic material is rigid, durable, and waterproof. This is the most popular material for checks that are Dry Erase because of it's smooth surface. Options include dry erase finish, filled in, or blank. The dry erase option is commonly used for checks that will be used multiple times. Blank checks are not customizable, to add logos and/or names and amounts, choose the customizable checks. These are the best looking checks on a rigid material. Shipping can be costly for these checks, but if you're looking for a reusable check, then this is the one. I personally like the Foam PVC the best because of the professional look it has. This is the best choice if you want your check to look of the highest quality. It is completely rigid, so we have to ship it flat. We custom cut our own box in order to fit this 30"x60" flat check into.
