Also known as mat board and museum board, this paperboard is often used to mount pictures or build architectural models and prototypes. Made of 100% cotton, it's stronger than traditional cardstock and won't fray when it's cut.

This paperboard is free of acid and lignin, chemicals that can damage paper and textiles. Plus, it’s made with fade-resistant pigment to prevent it from lightening or yellowing over time.

1-ply paperboard is about as thick as a business card. It cuts more easily than 4-ply paperboard, so is a better choice for model-making projects or light duty mounting.

4-ply paperboard is about as thick as a penny. Stronger and more durable than 1-ply paperboard, it’s suitable for mounting artwork, photographs, and other documents for a long time. Due to its thickness, cutting 4-ply paperboard may require several passes with a utility knife or paper cutter.
