These large reusable shopping bags are made of polyester fabric, which is lightweight yet sturdy. Each can hold over 50 lbs. equal to 2 to 3 plastic grocery bags-suitable for packing items like canned goods or milk gallons. Their seams are reinforced to boost durability, so they resist tearing under heavy loads. This set includes 10 black bags, enough for personal daily use, bulk needs, or activities like camping, storage, company events, and festivals. A key feature is their foldability: they can be rolled into a small zipped pouch that fits easily in backpacks, purses, or car glove boxes, keeping them handy for unplanned trips. These bags are machine washable, simplifying maintenance and allowing repeated use to stay fresh. Their plain black design also works for DIY customization via silk screen printing or heat transfer, making them fit for branded items or personalized use. Whether for daily errands or special occasions, these bags offer functional, flexible storage and carrying solutions.
