Rated 4.3 out of 5 by 3 reviewers.
Rated 3.0 out of 5.0 by Not exactly what I expected. YOU MUST BUILD THIS YOURSELF - NOT ASSEMBLED ! ! ! I should have read the extremely fine details that were hidden from plain view. You must fold this box together and then tape it closed. I wouldn't usually complain about this, but I also had to cut down the inside of the bends as well. The angles were cut to be 90 degrees, not made for a triangle. August 16, 2016
