4910F transparent foam tape in 40mm x 19mm rectangles. Made by 3M, this tape is made from a thin (1.1mm) flexible foam with adhesive on both sides. There is a red easy-peel liner one one side of the tape and a plain liner on the other. Once the liners are removed, the tape is completely clear & ideal for glass/perspex where an invisible fixing/fastening is required. This is a pack of 8 VHB adhesive rectangular pads.
