NOTE: Standard sheets of foam are cut slightly larger than the listed size to compensate for shrinkage during packaging, transit, and delivery. Sheets may contain rough edges. Any yellowing/discoloration present is a byproduct of exposure to light during production and manufacturing and does not represent a flaw, damage, or defect in the material.
