Where to start. I bought brandnew, and received a used product, no shrink plasti. And lots of dust and smudges from whom ever opened the box before me. The little containers are free sitting in the back and have 1/4" runners on each side for maybe 2" so i wouldn't use them for heavy objects. Some of the squares with runners are warped so the boxes sit a bit crooked. And dont quite slide in all the way. Im wipeing someone else's pencil shavings and dry erase dust off the front along with a mysterious brown smudge...hmmm. im not impressed at all.. i dont think ill buy from iris again ill pay more for a higher end brand. Shipping was fast item was received within 72 hours of placing order.
