Box of 10 rolls of #4 refills for MMLD Wire Marker Dispensers. Each individual marker is mounted on a silicone release liner and has an acrylic adhesive, which is resistant to oil and water, and has a usable temperature range of -40íF to +176íF. The marker itself is made of Tyvek¬ to assure durability and minimize the potential of tearing during application. Simply pulling down on this liner feeds the marker from the dispenser and makes it ready for application.
