Cork is an environmentally responsible, naturally renewable resource. Cork is harvested from a cork tree, stripped with careful cuts that do not harm the inner core of the tree. The cork bark regrows, and this process allows a useful life of more than 150 years for each tree. Self-adhesive skins feature a .25′′ thick layer of natural cork with a peel-and-stick backing to apply easily to an existing board. CAUTION Self-stick adhesive is intended for resurfacing on an existing board surface and has not been tested for use on other materials. Manufactured in the US of foreign and domestic materials.
