Zipper - We have found that the zipper is the most prone to damage when using a normal laundry bag Large Mesh Holes - Generally, due to the extremely small holes of the bag, water is not easy to flow out, stains and detergents are difficult to be rinsed off, and even drying will be weakened. In contrast, our laundry bags are designed with a honeycomb structure whose coarse mesh allows soap and water to flow easily without compromising cleaning and drying efficiency. Provide essential protection for your delicate clothes &nbsp: NO FLUORESCENCE - All materials we use are fluorescent free, including bag fabrics, YKK zippers, and even sewing threads and labels. We care about every detail to ensure that your delicate garments do not fluoresce and reduce any potential risks to the health of you and your family. Build Quality, Robustness and Durability - Our modern factory is ISO and BSCI certified with strict hygiene standards and regulated technical processes. Each bag is guaranteed safe, non-toxic, and well made. Multiple tests have proven that the laundry bag is still as good as new even when it is severely torn by a grown man. They are absolutely durable PACKAGE INCLUDES - You will receive five bags that are commonly used by most households, including 2XL (60cmx60cm), 2L (40cmx48cm) and 1M (28cmx40cm) for laundry.
