Welcome with Dog & Cat - This blank template comes with multiple layers and is 18". The base layer is 1/4" thick MDF. The top pieces are 1/8" thick MDF. Pieces require glue to be attached to each other. All MDF pieces will be blank, unpainted and unassembled. *You will receive laser cut pieces that have black or dark edges, but can easily be painted over. Because this is cut with a laser, it may have a slight smell of burnt wood.
