I ordered these shelves and they arrived later than expected.  But I was still excited to get them because I hadn't found anything like them here.  I had ordered one in the largest size and two in the smaller.  When I unpacked them the larger one looked good, but the two smaller had hairline cracks in the bottom edge on the short side that sits perpendicular to the wall.  I was mad.  It was going to be a while to return them and get new ones back.  So I bought some wood glue and glued the crack and hung them anyway.  They look great in my daughters room and I had waited long enough for them and didn't want to wait for the return.
