ممحاة ديروينت تعمل بالبطارية، تحكم دقيق، أداة مسح قابلة لإعادة التعبئة

The tip is fine and sharp, allowing you to target tiny stray lines and delicate corrections without affecting surrounding graphite. This makes it especially suitable for technical drawings and fine artwork where precision matters.

Key specs include: battery-powered operation for consistent erasing power, replaceable eraser tips, an ergonomic, compact, lightweight body for on‑the‑go use, and graphite‑friendly erasing that minimizes smearing.

Remove the spent eraser tip from the tip chamber and insert a new refillable eraser tip until it seats securely. If your model has a cap or sleeve, reattach it after the tip is replaced.

It’s designed to cleanly erase graphite from pencil drawings and technical sketches, making precise corrections with minimal smearing. It’s primarily for graphite, not for ink.

Keep the exterior dry and wipe away graphite dust gently with a soft cloth. Periodically clear graphite debris from the tip chamber and avoid getting liquids near the electronics. Use only the recommended replacement tips to maintain performance.

Ideal for technical illustrators, architects, product designers, and fine artists who need precise corrections in drawings, architectural plans, diagrams, or detailed illustrations.

Hold the tool like a pencil, use short, light strokes, and move slowly for accuracy. Apply gentle pressure and let the tip do the work rather than forcing it. Turn off the device when you’re not erasing to conserve battery life.
