[Vacuum Technology] These carpet grippers can be easily stuck under any carpet. Using vacuum extraction ensures a firm grip on the floor and keeps the carpet in place, stopping curling and sliding. Thanks to the slight elasticity of the vacuum technology, the carpet tape adds comfort underfoot. Adapts to carpet corners, round carpets, area rugs, carpet edges, corner rugs, etc. Eliminate curled corners in the kitchen, living room, hallway, bathroom or bedroom. [Zero-Mark Suction]: Unique suction technology ensures a firm grip to touch the floor and easy peel-off functionality without leaving marks on the contact floor. The floor-facing side has many tiny air holes. When pressed hard enough, air escapes outwards, creating a negative vacuum in the air holes, creating a bonding effect that holds the carpet firmly in place.
