You receive your quantity of choice of jumbo puzzle pieces. They can be joined together as shown. These are bare 0.30 gauge chipboard. Each puzzle piece measures 9 9/16"w x 7 3/4"h. Your choice of basic 0.30 weight or a thicker 0.50 if you want to embellish paint or adhere items, I recommend the thicker. Last photo shows thinner on left, thicker on right.
Use chipboard as is, rubber stamp on them, ink them, paint them, cover them with paper, etc, etc.
Chipboard is a type of paperboard/cardboard made from reclaimed paper stock. It's the cardboard you would find at the back of a legal pad or notebook. It may include small inclusions, spots or freckles here and there. This is not a wood product.
