Work quite well and will be useful. Plastic is cheap looking and not sure about the quality.

Overall I really like these Fresh Pouches. They are easy to wash, dry and reuse. My half avocado remained fresh for 3 days requiring only a minor surface scraping to remove a very thin darkened layer of flesh. The avocado pouch is however a bit tricky to reopen. I’m still trying to master that. My half onion remained nicely contained in its container with no aroma seeping out into the refrigerator. The smallest pouch, the round yellow one fits cut up lemon pieces or a small half or less lemon. I was unable to get the pouch to close with a half of a larger lemon. Solution is just use one of the larger pouches and the half large lemon sits nice and snug inside with no problem closing or opening its larger pouch. So far I haven’t tried any other fruits or veggies but all this said, I am happy I purchased this item.

Very easy to use
