Compact reusable bags make it a lot easier to always keep a bag with you, so you don't actually have to "remember" to bring a bag. This makes them perfect for those unexpected shopping trips. ***** IMPORTANT PLEASE NOTE ***** These bags are designed to be incredibly easy to compact, and require no folding, and no cumbersome zippers. As a result, all you do is simply scrunch the bag, but it certainly means that it does get a bit wrinkly, especially when the bag is new and first opened. While the bags can not be ironed, because they will melt. They can be wet and then put in a dryer on a low setting for about 3-5 min. This should take out most of the wrinkles. The bags also loose most of the winkles with use and when you put something in the bag it will pull out most of the wrinkles. The care instructions for the bag can be found on a care tag located inside the bag body.
