It is a metal letter holder with a couple of sections. For $1.00 it is great.
It holds the smaller specialty rulers with no holes for hanging. It sits on a small dresser that is stuffed with fabric.
Being a metal mesh you could wire it to a peg board. I wish I had bought the whole set before they sold out. It was really nice office stuff.
I shop at Dollar Tree. Also 99 Cent Only Stores.
