SELF-ADHESIVE CUSHION: Save time and eliminate the use of cements with our Self-Adhesive Cushion. This black PVC material is just resilient enough for good impressions every time. Not too hard and not too soft! The super sticky adhesive is applied to both sides and covered with waxed paper. Remove the waxed paper to adhere your stamp die to one side, then trim with a die cutter or cutting shears. Adhere the other side directly to your wood or plastic mount block. 1/16" or 1/8" thickness in 12" x 18" sheets can be ordered on line. 18" x 18" or 18" x 36" sheets are available for order by phone or fax (will ship at a higher UPS "oversize" rate). PLAIN CUSHION: The classic sponge cushion used extensively throughout the art stamp industry! It is carefully manufactured to assure quality of materials and has a surface textured for cementing rubber dies. Made of real red rubber. 1/8" thickness for the right amount of resiliency required for stamp die mounting. Supplied in your choice of 12x18" or 18x36" sheets. Use our Rubber Cement to attach the rubber die to the cushion and contact cement (available at most hardware stores) to attach the cushion to the mount.
