What does self-healing mean for a corkboard surface?

A self-healing corkboard surface is made from natural cork that fills in the small holes left by push pins or thumbtacks after they are removed. The cork's natural cellular structure compresses when punctured and expands back to near-original form, maintaining a clean appearance over years of use. Self-healing cork is the standard for commercial corkboards. Low-quality synthetic cork does not self-heal. OfficeFurniture2go.com carries natural cork corkboards — call 1-800-460-0858.
