The design is very sleek and allows me to quickly pin work in the hallway or wherever WITHOUT staples, thumbtacks, t-pins or other nonsense. When I decided to order more I found them on amazon and staples and they are a bit pricey, but I've decided to invest in this timesaver. I swap out 28 artworks every week to have a rotating "Artist of the Week" represented from each one of my classes. My previous system of thumbtacks and binder clips was functional, but not this easy. With the binder clips, if you don't find the exact center, the artwork would hang lopsided. If I was hanging 12x18 or larger I needed two clips. These are sturdy enough to only need one, which means I can hang up in half the time. And, if you're like me, you won't have to run back to the art room when you are hanging up your 3rd of 25 artworks and realize (again) that you're out of staples. Every. Single. Time.
