Also, please understand that there is a difference of a few mm between the outer and inner dimensions. ◉Folded for packaging & shipping ◉When folding, it may be folded in the opposite direction of the side to be assembled, so please be aware of this. ✅During the cutting process, cardboard fibers may adhere to the boxes.
