Review on 📦 BOX USA B4412 Corrugated Boxes: High-Quality Packaging Solution for All Your Shipping Needs by David Naranjo

I don't ship anything inside. I can if needed, but not yet. It looks like they will travel by mail with no problem. As rat houses, however, these boxes are perfect - just the right size, and my rats don't destroy corrugated cardboard as quickly as shoe boxes, and most shoe boxes are too big. So I attached them together with a few drops of E6000 or craft glue, let them dry completely, cut a small hole in one side, and the rats enjoy their new home for at least a month. They eventually destroy the box, but there are twenty-five of them in the pack. Also can work for some other small pets.
