The Inart Electric Eraser Refills 2mm and 5mm (15+15 units) (110699005) are replacement consumables for the Inart Electric Eraser, containing 14 refills. This allows you to continue using the eraser after the original refills have run out without having to replace the entire eraser or buy a new one. The package includes 15 2mm refills, suitable for small details and fine corrections, and 15 5mm refills, more suitable for erasing larger areas more quickly, thus covering the two most common needs when working with dry techniques. Each refill fits directly into the electric eraser, without the need for additional tools or glue to replace the worn tip. It is ideal for those who already own an Inart Electric Eraser and regularly work with dry techniques such as graphite or charcoal, needing to replace worn refills over time.
