This cute and colorful round wall protector is made from environmentally-friendly rubber, high silicone gel, a soft door stopper, and unbreakable and non-cracking headboard bumpers. Adhesive bumper pads allow you to protect your wall and door knob when the door is vigorously closed by a cat, dog, or baby. Wall bumper guards can protect the wall and door handles, glass windows, and furniture. Door bumpers for walls have excellent sticky self-adhesive backs which can be firmly stuck on door stops, and wall protectors from doorknobs. Wall door stoppers perform better than 3M door sticker plastic against door slamming. The wall door knob protector slows the impact and acts as a noise absorber from door banging. - Material: Silicone - Size: Diameter: 5cm - Color: Pink, blue, purple, white
