"The original and the best by far !"
I've tried the cheap alternatives but keep returning to these. They are particularly great for "make- ahead" freezer meals. Just chuck all the raw ingredients for your meal in the bag, expel the air, flatten it out and throw it in the freezer. The night before you want to cook it, move the bag from the freezer to your fridge. In the morning, pop the thawed ingredients straight into your slow cooker/crockpot and turn it on low. Come home to the great smell of food cooking and a tender tasty home cooked meal.
The difference is that these bags are TOUGH, DON'T LEAK, and SEAL PROPERLY.
They are a lifesaver !
