I have been using these boxes now for a couple of years. I use them to store all the yearend records in. They have been stacked four to five high. Daily they are exposed to dust from a trailer repair shop. Also they are exposed to the Hot and cold of the shop. The boxes are dusty but the records inside are just fine! I would highly recommend them for storage.
Great sturdy storage boxes. I was able to stack then 8 high in my storage area. the corners held up great and I have even been able to re-use them since they are so well designed.
I have been using this boxes in years now. They in good price easy to fill in easy to lift and store perfect headings to show what is inside the boxes!
