✨Brand New✨ These are interlocking mats with non-slip processing to prevent falls. I've been using them myself, and I kept spares for my beloved dog's old age, but I no longer need them, so I'm selling them. A large quantity of 60 mats, so you can protect a large area. Size: 30 x 30 cm (per mat) Thickness: 4mm (per mat) Quantity: 2 sets (30 mats x 2) Color: Navy & Dark/Light Gray (10 mats each per set) 【Non-Slip Adhesive Tile Carpet】The mats stick together as if countless suction cups have formed due to air escaping and creating a vacuum. They won't slip even when you move around. The mats are about 4mm thick, so you won't trip, and they won't obstruct the opening and closing of doors. There's less risk of catching on them. They are good for elderly people and older dogs as a non-slip measure. 【Easy to Install, Customizable】You can easily change the image of your room just by laying out the interlocking mats as needed. They can be easily cut with scissors, and you can stick them perfectly to every corner. 【Wide Applicability】Many places to use: ① Around the entrance (convenient for preventing floor scratches and stains from bicycles and chairs) ② Hallway (for elderly dogs and the elderly as a non-slip measure) ③ Kitchen (if you drop glass or ceramic dishes, they absorb the impact and are less likely to break) ④ Indoors (ideal for soundproofing to absorb and reduce the impact of falling sounds and the sound of pulling chairs), etc. 【Material with Heat Retention/Durability/Antibacterial Properties】■ The back is made of upgraded polyurethane material, which is softer and more durable than other products, and does not leave a sticky residue on the flooring even after being attached for a long time. It has excellent heat retention, so you don't have to worry about the cold on cold flooring in winter or with air conditioning. ■ The surface is made of special fibers containing silver ions, which have high antibacterial, deodorizing, and anti-mold effects, keeping the mats clean. 【Easy to Clean】Easy to care for as they are compatible with vacuum cleaners and robot vacuum cleaners. If they get dirty or damaged, you can remove only the dirty part and wash it in the washing machine.
