Choose either a 4 or 8 pack of ready to go erasers for your bullet pencil. White, pink or mix them up.
If you're buying the Bullet Pencil as a gift, or even for yourself, you obviously like writing with Pencil (A VERY cool, rugged, classic, vintage pencil) because you like to be able to erase any mistakes. Don't get caught without an eraser. Buy a few extra to give with the Pencil or keep for yourself.
