These are VERY high quality, extra-heavy-duty, double-draw, soap nut wash bags. They have heavy stitching up both sides and across top. Large, over-sized 3"x4" bag makes locating the wash bag very simple. They typically last for many months - far superior to lightweight, single-stitched, single-draw cotton wash bags that are commonly sold with soap nuts and frequently fall apart after a few loads. Each bag is constructed of heavy, durable muslin fabric. The tough, rugged, tightly wound cording makes opening and closing very smooth - easy for tying and untying over and over. Rest assured they will hold up under the harshest washing conditions, and last for many, many loads. NO INKS to come off in your wash - or possibly stain fabrics! Unprinted, all-natural material makes for an absolute minimal carbon footprint. 3 wash bags per set.
