Non-slip stickers, 8 pieces New, unopened Sticker size: Diameter approximately 4 cm These non-slip stickers are peeled from the backing paper and applied to the back of a mat. Originally, these were non-slip stickers that came with a video game where you step on a mat in time with the rhythm. I am selling them because I didn't use them. The game console mat was made of nylon. Image 3 is a reference image and is not included with the product. I do not know the non-slip performance, durability, or adhesive strength of the stickers as they have not been used. These have been stored at home. Please refrain from purchasing if you are sensitive to such things.
