These bags are simply amazing. Not only am I doing my part to reduce plastic waste, you can do so much more than just store food in them! Last night I used them to marinade salmon (extra spicy in one bag for my husband, regular for me in another) and then put them straight in the oven with no mess. Highly recommend. This multipack is great for getting started and you'll quickly see which sizes you use the most frequently so you can order extra of that type.
