First off, I was super excited to find these adjustable boxes for shipping my large artwork. The idea of a customizable size seemed perfect for my needs.
The good: When I received them, the construction seemed decent enough. They're made of corrugated cardboard and come in multiple pieces, which you can adjust to fit your item. I used them to ship two 24x30 paintings overseas, and they held up surprisingly well with enough bubble wrap and tape.
The not-so-good: Let's be real, these boxes are THIN. Like, 'I-can-see-through-them-if-I-squint' thin. If you're shipping anything remotely fragile, you'll need to go heavy on the padding. Also, assembling them is a bit like playing Tetris while blindfolded – frustrating and time-consuming.
Pro tip: Use an ungodly amount of packing tape. Seriously, more than you think you need. The cardboard doesn't hold tape well, and the last thing you want is your box falling apart mid-shipment.
Final verdict: They get the job done if you're in a pinch (and have patience), but don't expect premium quality. For the price, I'd probably look for sturdier options next time unless I absolutely need the adjustable feature.
