The prismatic pattern resembles the look of a fresnel lens or machined metal (but are not night-time reflective).

They can be used on dance & exercise hoops, car dashboards, picture frames, fishing lures etc.

Small rolls are 36 feet long (enough for two hoops) and are wound on 1-inch diameter cores.
330-foot rolls are 8-1/2 inches in diameter.

Decorative Tape (Adhesive) These tapes use a solventless, non-toxic, non-polluting adhesive, and comply with the European Union RoHS directive, which limits the concentrations of lead, mercury, hexavalent chromium, cadmium, PBBs, and PBDE.
