I bought this item on Amazon to sort my cardstock papers and construction papers. This is super easy to assemble, almost like origami, and very durable. Also, the outside of the sorter is printed, so it doesn't really give that cardboard look. I read some reviews on Amazon complaining that this is cardboard, well, it's written in the description that this is made of cardboard. What I really like about this is that since it is cardboard and not wood, it is light enough that I can easily move the sorter around. I definitely recommend this sorter!
