That's Crafty! Surfaces MDF Uprights - - Jagged Edge - Pack of 5. These Uprights are 4mm thick and our MDF features an extremely smooth surface, so there is no need to sand it before you start decorating it. Each set of Uprights contains 5 Uprights and 5 Bases.
Our MDF is precision cut on a laser machine and as a result, there is black residue on the cut edges of the uprights which does not affect the quality of the product in any way. It actually makes a very nice decorative feature if you choose not to paint it!
