These are indeed self-adhesive anti-slip furniture pads, but in a slightly different form than the typical pre-cut pads. These are rolls of material that you can cut to the desired size. Here’s a breakdown of what we see in the image:  

• Rolls of Material: Instead of individual pads, we see rolls of a woven or mesh-like material. This allows for greater customization in terms of size and shape.
• Self-Adhesive: The material has an adhesive backing, allowing it to stick directly to the furniture legs.  
• Anti-Slip Texture: The woven texture provides grip, preventing furniture from sliding on smooth surfaces.
• Protection: Like traditional pads, these also protect floors from scratches and reduce noise.  

Here are some potential advantages of this type of self-adhesive furniture pad:

• Customization: You can cut the material to fit any size or shape of furniture leg, which is useful for irregular shapes or large furniture.  
• Versatility: You can use it on various types of furniture and even other objects that need to be stabilized.
