Our hat box shape and sizes have been produced exclusively for Hat Boxes USA. Each one is made with 1/8″ thick corrugated material to withstand years of wear and tear. They are hexagonal in shape so they can collapse flat for easy storage and shipment from our location. We offer 3 sizes to fit comfortably a small fascinator or hat, an average sized brim hat, to an x-large Derby hat with a depth of 9″ to accommodate large embellishments. Each one comes with a cord for easy carrying.
