The listing, standard staples for school has ended.
These are a bunch of unused standard staples.
I have them in a box that says:
"Swingline standard staples 35-2D" although I am not sure whether this box actually belongs to these staples.
However, I compared with other Swingline standard staples that I have (which are much shorter) and they look the same width and height so most likely it should work. There are 3 long ones so these are mostly good for a long stapler. If you have a short stapler, no problem, you can break the length anywhere you like.
Just a caveat, though, that the staples aren't as shiny as other ones I have.
