Really it's a roll of tape - Law Enforcement Targets Self-Adhesive Target Pasters 3/4 Inch Square White 500 Per Roll PASTERS-WHITE

This product is simply a role of precut tape squares. A roll of masking tape would do the same thing albeit with less convenienience. You need to weigh the value of that convenience but it works for me. The squares do peel off easily and have good adhesive quality. What more is there to say? These get the job done, fit easily in my range bag and are there when needed. I will say that I have changed my routine at the range and change targets much less frequently. Now I simply tape up misses and keep going.
