6pk means I can scatter them in every pencil case and drawer, which is exactly what I did. The refills fit my mechanical pencil without any wobble and erase cleanly enough that I don't have to press hard. Good value for the number you get.

The eraser refills slide right into my mechanical pencil and grip the lead firmly—no slipping mid-correction. They chew through graphite cleanly without smudging the paper, so my sketches stay sharp until the last stroke.

The 6-pack means I can keep one in my pencil case, one on my desk, and still have backups for when I inevitably lose the rest. The refills fit my mechanical pencil perfectly and the black color hides grime way better than the white erasers I used to buy.
