Review on 20-Count Clear Glass Table Top Bumpers: Ultra-Soft & Non-Adhesive | 3mm Thick Glass Spacer by Rud Starks

Two different side tables have been repaired. Bought a glass panel for one and plexiglass for the other and these bumpers/eyelets to protect the new panels. After several days of checking, dents and stains remain on two countertops. Both will be destroyed. Cannot be washed off with soap and water. Very disappointed. What was supposed to protect my countertops ended up damaging them. I did some research and saw reviews here that said people had had success with these items and had no stains or damage. Well my experience was different.
