Using your Keith Haring Standard Shopper Bags is a breeze. You can carry them by hand or throw them over your shoulder to tote up to 50lbs of your belongings, which is about the same as 2 - 3 plastic grocery bags. When you're done using them, just fold each bag into its own 5' × 5' flat pouch for easy storage. To keep your bags looking great, they're machine washable. However, always follow the standard machine - washing instructions on the care label. Store the bags in a cool, dry place and avoid leaving them in direct sunlight for long periods to prevent the colors from fading. The reusable drawstring pouch they come in can also be reused for other small items, so don't throw it away!
