Our cork tackboards are made from high-quality, finely grained 100% natural cork. Cork is a durable,resilient material that recovers quickly from tack or pinholes. Our tack boards are factory framed in anodized aluminum or wood and are ready to hang. The 1/4" fine grain. pure natural cork is bonded to 1/4" MDF. This provides ultimate tack-holding power and deeper tack penetration. Boards include L-clips and mounting hardware.
