Manufactured using a sturdy, single wall board grade, these brand new cardboard boxes will carry decent weight, once loaded. We have a one off, single batch of these cardboard boxes available after a recent product line change from a manufacturer's customer, rendered these cartons obsolete. If you need a small, strong packing box to ship your goods, then look no further than these! They are cheap in comparison to alternatives you'll find online, especially considering the board grade used and their excellent condition.
