The highest quality oil only absorbent pads on the market. They are used to absorb oil and petroleum-based chemicals. The fine-fiber polypropylene increases the strength and durability of the pad, allowing them to be perforated to help reduce waste by allowing you to use the size pad that you need. The fine fiber enables the pads to grip surfaces securely. They are low in lint and the extra durability allows them to last longer in higher traffic areas. Each pad is 15"x19" and perforated vertically every 7.5" and horizontally every 19".
