The image shows a close-up of a set of four black rubber mats with a perforated pattern. The mats are arranged in a diagonal line, with each mat slightly overlapping the one below it. Each mat has multiple holes in the center, creating a grid-like design. The holes are evenly spaced and appear to be made of a shiny, metallic material. The background is a light green fabric, which contrasts with the dark grey of the mats.
