A cardboard casket includes a top piece and a bottom piece. The top piece is formed by making a single press die cut in a reinforced core cardboard panel, including cutting the reinforced core cardboard panel to form the top piece and forming seams in the top piece. The bottom piece is formed by making another single press die cut in another reinforced core cardboard panel, including cutting the other reinforced core cardboard panel to form the bottom piece and forming seams in the bottom piece. Cutting the top and bottom pieces includes cutting through a first layer, a reinforced core, and a second layer of the reinforced core cardboard panels. Forming seams in the top and bottom pieces includes deforming the first layer in the seams, deforming a majority of the reinforced core in the seams, and leaving the second layer in the seam uncut.
