Uni Pencil Eraser Refill Size S - Pack of 5

These mini eraser refills have a tendency to run out quickly(cause they are tiny), and they are quite expensive considering the small quantity provided. They are priced at 92 cents per eraser, which seems excessive. I believe that these erasers would be easy to manufacture, the price should be more reasonable.

Unfortunately, the erasers are the wrong size for my mechanical pencil and I can’t use them.

I finally found Uni Pencil Eraser Refills

I have been looking for these for ages and our local stationery stores didn't have them.
