NO, they do not work. I put bananas in one and they stayed yellow but rotted on the inside. Had the bananas in the green bag for 3 days and had to put them in the garbage. They are a waste of money. I through the green bags in the garbage along with my bananas. We bought the bananas and put half of them in the green bag and the other half on the banana stand, the ones on the stand out lasted the ones in the bag.
