I have purchased another brand of this item before. The ones from Staples are of lesser quality. Staples’ are more difficult to open and the arms do not line up properly to simply push them closed. The arms on some cross behind each other so as you are trying to close them the arms need to be torqued to allow them to overlap properly and close. If you are using them in situations where opening and closing is infrequent they are OK. If you need to do so frequently I would suggest searching for another brand.
I had never seen colored book rings before and bought them because they were the same price as the regular ones! These help since school went all online from the shutdown I also use Staples to print off packets and chapters from textbooks for my classes; that's very cheap as well. If it weren't for Staples I wouldn't be able to pass my classes!
