This is a Faber-Castell 1600 drafting brush from the German stationery manufacturer Faber-Castell, a long-established company. Main Features and Uses: Uses: Originally used in drafting to brush away eraser shavings from drawings. Directly brushing with your hand can smudge the drawing with oils from your skin, but using this brush allows you to keep the drawing clean without damaging it. Usage scenarios: Besides drafting, it's popular as an "excellent cleaning tool" that can be widely used for cleaning around the desk, cleaning keyboard crevices, or collecting breadcrumbs in the kitchen or at the dining table. Material: The brush part uses very soft goat hair, and the handle is made of wood.
