3/8" Black Back Foil - 1.25 MilVenture Tape

Use black backed foil on clear and transparent glass, mirrors and bevels. Its black, non-reflective backing matches well with black patina. Extra-wide, use with thick glass or when the strength of your project is important.

Telling your foil apart is easy with Venture Foil Tape. The inside ring for 1.25mm is always orange for easy identification.
