?This handy combination of 15mm masking tape with opaque plastic sheet attached allows you to mask with precision, using the sheeting to cover large areas and saving time otherwise spent taping the whole area to be masked. ?The width of tape and sheeting combined is 150mm, perfect for use on 1/24 scale car models. This roll is 10m in length. ?Polyethylene sheeting offers good resistance to thinners and is actually a dual layer that can be cut to make it into a larger sheet.
