3mm Cork Roll – 1/8" Natural Cork Roll for Bulletin Boards & DIY

The 3mm cork roll — sold in both metric and as 1/8-inch cork roll — is the highest-search-volume cork roll thickness and the go-to choice for DIY bulletin boards, wall cork panels, and light craft projects. At 3mm, the cork is thick enough to hold standard pushpins securely while remaining flexible enough to roll flat against a wall or fiberboard backer. This thickness is widely used to resurface existing bulletin boards, create custom wall-mounted cork panels, line tool pegboards, and as underlayment beneath lightweight flooring. BangorCork's 3mm roll is made from 100% natural Portuguese cork — self-healing after pin removal, hypoallergenic, and sustainably harvested. Available in 4-foot-wide rolls in multiple lengths. Cut easily to any dimension with a sharp utility knife or straight edge. For high-traffic pinning or heavy pushpin use, consider the 6mm roll for added holding depth.
