The packaging Styrofoam (EPS foam) broke inside of packaging, which I understand it's inevitable during transportation ,  but it seriously made a big mess for me to take parts out and  assemble it, It took me 20 min to assemble, and 30 min to clean up the mess. and 40 dollar to buy the bookshelf, and 10 dollar to recycle Styrofoam. Would not buy it again.
