MATERIAL: * Glue Dots: Synthetic rubber based
USAGE: * Note: All types of glue dot rolls have 12 - 15" of surplus liner (from the last dot to the core). This is a manufacturing feature required for smooth operation. * Glue dot rolls come with black lines on the liner outlining each dot. * All Glue Dots are acid free, but the low tack has mineral oil that can leave marks.
