Review on MT Products Inches Paperboard Non Window by Adam Browning

I would really like to be able to contact customer service or the seller directly. The boxes are great and the perfect size for what I need. But it looks like one of the boxes wasn't cut properly. One of the flaps was too small and didn't close the box properly. I compared the damaged box with the undamaged box. You can see the flaps are smaller than they should be. I can't assemble the box because it won't close. Please contact customer service :)
