Thanks! I could not find another thread…sorry.
NO one seems to flatten them but I just can’t find the room for every box in it’s original form. I will pick and choose I guess which I am keeping original and which will be flattened or tossed. It definitely increases eBay value to have the box but mostly that is for original boxes…again, not sure I have seen flattened ones out there. UCS sets I definitely keep the boxes as is but the other sets will be a toss-up based on room and re-sale-ability I guess…or cool pics!
