A great set of bags to use with your Zwilling Vacuum Pump, these bags are very versatile, great for storing meats, veggies, fruits in the fridge or freezer. I’ve used mine quite a bit for veggies like kale, and love how compact it becomes once sealed, but when I open the bag, the kale is vibrant and bouncy, definitely not squished. Easy to clean, these are a great reusable bag set, perfect for storing food, using as for sous vide.
