These Greenboxes are WONDERFUL! I use them for bread, veggies, and fruit. The lettuce holder keeps my lettuce 4-5 weeks (WOW!). I de-core it, wash it, drain it, and put a paper towel under the drainer bowl, and then the lettuce and lid. EACH TIME I OPEN ONE, I WIPE OFF THE CONDENSATION FROM THE LID AND CHECK OUT THE PAPER TOWEL IN THE BOTTOM TO MAKE SURE IT'S NOT SOAKED WITH WATER(VERY SIMPLE). Pay attention to the condensation. That's the secret... I have also saved lots of $$$ by using them.
