Premium Uni Mechanical Pencil Eraser Refills (SKS) - 12 Pack - Compatible with Most Mechanical Pencils - Perfect for School, Office & Art Projects

Good eraser! Very small and I ran out, so I bought these and had them in my hands in two days, even less than was originally projected. My only complaint, and not really that, was that the box was huge. It was kinda cute how gargantuan the box was in comparison to the erasers. Would buy again.
