My binder hole punch is an integral piece of my college stationery kit. I own the pink one from Staples!
As someone who has problems looking at screens for too long, I often print my class materials out. The binder hole punch’s function is pretty straightforward and this one does the job perfectly: I use it for class handouts and for the materials I print out myself. It’s lightweight and I can carry it around in my bag/binders or leave it on my desk, where it matches well with my other pink stationery. It can punch multiple pages at once (I’ve done up to 5) despite not being heavy-duty. From a design standpoint, it is desirable for me because it is both functional and aesthetically-pleasing – it’s a nice decorative addition to my desk but it’s also a crucial part of my academic life.
