The laundry bag helps separate dark and light clothes to prevent dye transfer, and can also wash baby clothes and underwear separately to avoid crosscontamination and support healthy washing. It reduces friction and pulling in the washing machine, prevents deformation and pilling of silk, wool and other fabrics, protects sequins, embroidery and other decorations from coming loose, and prolongs the life of clothes. It is subdivided into fine mesh, coarse mesh and different sizes. The fine mesh protects delicate fabrics from snagging, the coarse mesh provides stronger decontamination for heavy clothes, and the three dimensional shape accommodates exclusive needs such as sweaters and underwear. Designed for simple operation with an integrated zipper, the bag keeps clothes sorted and untangled after washing, rinses clean with water, and dries quickly without taking up extra space. Use scenarios Daily family laundry with mixed colors: use the appropriate mesh size to separate dark and light fabrics and reduce dye transfer while washing. Washing baby clothes or underwear: keep these items separate to avoid cross contamination and protect sensitive skin. Delicate and embellished garments: use fine mesh for items with sequins, embroidery or delicate fabrics; use coarse mesh for heavier items to ensure thorough cleaning while preventing damage.
