I reinforce the original boxes with new cardboard and packaging tape. I use a thin piece of steel bar, and hammer, to create the crease for bending a sharp corner.
A little pricier option but I have been happy with these. They are all plastic so I also use them to sanitize and drain my bottles before filling. I have had them for over a year and a half and have moved with them several times. Still like new. Sorry about the crappy pic. The company is C&W crate company
