I have acquired close to a dozen Menards items that did not come with outer boxes. They only have the plastic clam shells.
I've looked at the BCW boxes and of all their boxes, only 2 fit.
I guess I would need more details about your Menards items as to why the BCW boxes wouldn't work. They're the only boxes I use for the majority of my box-less fleet...PW, kit-built, modern.
The fact that fewer BCW card boxes cover most of my needs is an advantage...IMHO. It makes stacking on shelves more consistent, easy. Frankly, the one-size-fits-all idea I see as an advantage when looking for consistent shelf storage. Likewise, their absence of other product decoration/information (basically all white) on the boxes provides better shelf storage appearance...you know, that Sheldon/Monk 'thing'?
Our LHS games department carries the BCW card boxes from time-to-time in various sizes. They're far sturdier that the 'flap' styles of boxes, and still a good value for the price. Again...IMHO.
They work for me, anyway. Yet, TEHO.
