Durock Polyurethane Switch Films (120pcs)

These new switch films from Durock are made of polyurethane (same family of foam as Poron) and is 0.3mm thick. It helps the switch housings fit tighter and stabilize wobble, delivering a cleaner thocc.

Based on our internal testing, we found that the thicker 3mm polyurethane film helps housings fit tighter as it can compress for a snug fit, and it reduces 'ping' sounds that regular plastic switch films create.
