    Flimsy, poor quality

    Posted by Teresa on 29th Dec 2023

    I was really hoping these would work to mail out our small business items. We’ve always used slot boxes for our boxes, but I figured I would try out these boxes from Zakka as they came to 10$ less than the slot boxes from BC. Unfortunately, when comparing the two, the quality difference is obvious. The zakka boxes are thinner, with poor perforated lines, half of my boxes have tears along the seams which is not acceptable for presentation of items. The cardboard is so flimsy the side tabs do not stay firm when trying to close the box and when sending boxes via letter mail, every little mm counts! I would not recommend these for purchase and will never repurchase them.

    Boxes for Canada post slot

    Posted by Sil on 15th Dec 2023

    I bought the smaller boxes and they came quickly and were the correct size. There were some issues with the boxes and I reached out and spoke with the company about the issue. They were polite and quick to help out. I would shop here for future boxes. Thank you for all your help.
