The Technik eraser is a high quality clear eraser for all graphite pencils which leaves very little mess.  It’s extremely long lasting so you won’t need to replace it in a hurry. Established in Geneva in 1915, Caran d’Ache is a privately owned family company, making pencils to the high Swiss standard. Considered somewhat of a luxury brand, they are known for creating the first water-soluble pencils and inventing the clutch pencil. Made in Switzerland.
