Minamina per matita Staedtler 250 03-HB grigio

Lead refill Staedtler 250 03-HB Grey: a 0.3 mm HB mechanical pencil lead designed for precise, smooth writing and drawing on paper and drawing card. The lead produces jet-black grey lines with low breakage thanks to a flexible formulation. Manufactured using an ecological process without PVC or softening agents and made from more than 90% natural raw materials, these refills come in tubes of 12 leads and follow ISO colour coding for easy identification. Compatible with all mechanical pencils and offering a simple “12-a-go” refilling method for many STAEDTLER pencils, this product is suitable for everyday school, office and sketching tasks.

Advantages

The Staedtler 250 03-HB lead refill combines a fine 0.3 mm diameter with HB hardness to deliver clear, consistent grey lines and smooth gliding on paper. Flexible lead formulation reduces breakage during use, while ecological manufacturing without PVC or softeners and a high content of natural raw materials minimise environmental impact. Tubes contain 12 leads and use ISO colour coding for quick grade recognition. The refills are compatible with all mechanical pencils and include a straightforward refilling option for many STAEDTLER models.

Suitable for

• Precise writing and note-taking in school and office

How to use

Open the lead tube and insert a single 0.3 mm lead into the lead chamber of your mechanical pencil following the pencil manufacturer’s instructions.

Replace the spent lead with another from the tube; for STAEDTLER pencils that support the “12-a-go” system, insert the entire tube according to the pencil’s refilling procedure.

Recommendations

Store tubes upright at room temperature and avoid exposure to extreme heat or humidity. Use HB hardness for general-purpose writing and drawing; choose a different grade if you need softer shading or harder, lighter lines.
