You receive 3 bare 0.30 gauge acid free kraft colored chipboard frames. These are rectangular frames that have a thinner border than some of the others in my shop. Plain straight edge style. Each frame measures 4 7/8" tall x 4 3/8" wide and the opening is 3 1/4" wide x 3 3/4" tall.
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 may include small inclusions, spots or freckles here and there. This is not a wood product.
