Each adhesive strip is encased in four layers of plastic—three on top and one on the bottom.

Peel and remove the topmost plastic cling layer from the left adhesive strip.

Peel and remove the bottom plastic liner from the strip.

The top of the adhesive strip should still be covered by a colored plastic layer as well as a clear plastic stiffening layer.

The bottom of the adhesive strip should now be exposed and sticky.
