Purchased from Amazon in May 2023 and used for about a year. After that, it was stored at home, but I am selling it because I have no use for it. The following is a quote from the product description on Amazon: -------------------------------------------------- Swing Straps for Hanging Swings, Set of 2, with Safety Lock Carabiners, Set of 2 (Can be used as swing belts or hammock belts) 【Cross Stitching】 Cross stitching is applied to the D-ring parts at both ends of the straps, where the most force is applied. Durability is significantly improved compared to conventional straps. Weight capacity: 150kg. 【Double Stitching】 Unlike conventional products where the D-rings are sewn by folding the ends of a single strap, the entire strap is double-stitched. 【High-Strength Polyester】 Made of high-strength polyester material. Resistant to water and can be used with confidence both outdoors and indoors. Widely used for hanging play equipment such as swings, rings, hammocks, aerial yoga, and sandbags. #KenkoHands
