Review on IRIS USA MCC Plastic Clear Hobby Craft Art 📦 Satchel Storage Box Organizer 10 Pack with snap-tight closure latch, Medium by Kelly Caballes

I have ordered 10 packs of the IRIS Small Modular Accessory Case (Clear). The size is ideal for storing electrical parts on narrow shelves. They fold well and the latch keeps the box closed and easy to open. The problem and reason for the 3 stars is that there is either a design flaw or a manufacturing issue with the 'living hinge' design on the box. From the first order of 10, 5 boxes had the hinge broken on the left when viewed from the back of the box. Revain sent replacements. Of these, 4 had loop failure (left). So, out of 20 boxes, 9 had the same failure of the left hinge. In my opinion, this is a manufacturing defect in one of the molds or a design that does not allow large changes in production conditions. If this is a manufacturing issue, it strikes me as odd that 40-50% of both shipments contained boxes with the same issue. Either there is no good quality control or mistakes are deliberately mixed in. I contacted Revane hoping my concern would be escalated to IRIS. See attached photo of the problem. I will try to order medium boxes. Let's hope the lack of shape/design doesn't carry over to this design. See attached photo of the problem. I will try to order medium boxes. We hope, that the lack of shape/design does not carry over to this design. See attached photo of the problem. I will try to order medium boxes.
