These little bags are awesome. I have used them before, and decided to get more. They’re light, so don’t weight down the scales like cotton bags, and they’re made from recycled PET, making them much more hygienic. You can rinse veggies in their bags under the tap (I even spin mine outside with lettuce in them instead of using a salad spinner), and your things won’t go all soggy and juicy in the fridge. If you’re putting leafy things in them, be sure to keep them in your vegetable drawer, and set your fridge humidity higher so you don’t lose too much moisture. Wash them in your washing machine (I put mine in hot wash with towels).
