How to use

To replace the refill, keep the push button of the compatible mechanical eraser holder depressed and gently pull out the remaining eraser piece. Insert a new ER-KUS refill into the metal sleeve or holder until it sits securely, then extend to the desired length for use. Apply light to moderate pressure while erasing to prevent tearing or excessive residue; rotate or advance the refill as needed to expose fresh edges of the rectangular tip.

Usage recommendations

Store refills in a dry place away from direct sunlight and extreme heat. Use on standard graphite pencil marks; for ink or specialized media, test on a scrap area first or use a dedicated cleaning tool. Replace refills when worn to maintain effective erasing and avoid pressing too hard to prolong both the refill and the mechanical holder.
