Does the job without scratching my floors!

Im using these rug grippers to secure the throw rugs in my entryway and hallway. They do an excellent job in keeping the rugs from slipping on our wooden floors. 
They are easy to use, simply sweep the floor, then peel off the tape -sticky side first. Place the sticky side of tape on the rug and let the other side face the floor. The rug won't slip and the corners won't curl. In addition, this tape doesn't scratch my floors 
or leave a sticky residue behind. Plus, they can be reused when I want to clean under the rugs.
