These bags are amazing! #1) VALUE & FOOD FRESHNESS: I use them for fresh produce in the fridge - keeps kiwi, lettuce, romaine, bokchoy, celery, green beans and more fresh for over 2 weeks (before these bags, I'd have to throw out spoiled produce weekly, so I've saved a ton of money due to no food spoilage). Also work great for cheeses, lunchmeats and leftovers. #2) EASE OF USE: So simple, even a cavewoman could do it! Just put your food in the bags, press some of the air out, zip the bag and vacuum the remaining air out. Having arthritic hands, I really appreciate how easy these zip seal bags are to use in particular, just ordered a bunch more in the BOGO sale! #3) APPEARANCE: Nice bags, can write names and dates on them with a sharpie. What I love the most is that all my produce takes up less space in the fridge, making it look neater and it's easier to find other stuff! I DEFINATELY RECOMMEND THESE BAGS!
