I've purchased these several times and I would purchase them again. I agree with some other comments about the perferations though. Sometimes during assembly the perferations are not deep enough causing a tear in the cardboard. They're still useable when this happens but it's unsightly and frustrating. That said these boxes are quite good and I am sure that I'll buy more soon.
USE THESE ALL THE TIME TO STORE OFFICE FILES. RECENTLY WE HAD SOME WORK DONE TO OUR KITCHEN AND WE USED THEM TO STORE CABINET CONTENTS DURING CONSTRUCTION....GREAT...VERY ECONOMICAL...STACKABLE...KEPT EVERYTHING CLEAN AND SECURE!
