These socks are 4'(1.2 m) in length and three inches in diameter. The socks feature a tough spun-bond outer sleeve that has a durable heat sealed seam running its entire length. This tube is then filled with an absorbent chopped polypropylene core that is made from recycled sources. This core will absorb only oil-based fluids. The absorbent core is secured into the sleeve at each end with a durable metal clip. The spun-bond outer sleeve makes these socks very strong even when containing absorbed fluid, they are also a ‘no-lint’ product. The socks are very flexible which allows them to conveniently mold to any uneven surface
