Art. no. 250 03/05/07/09-... (degree)

The neck of the lead tube is simply inserted into the end of the mechanical pencil - all twelve leads can be filled into graphite 760, Mars micro 775 or graphite 779 in one go!

Advantages:

• No touching of lead
• No dropping of lead
• No breaking of lead

The identical colour coding of mechanical pencils, mechanical pencil leads and technical pens facilitates recognition of the different line widths.

Efficient and environmentally safe - that's the idea!

• More than 90% natural raw materials
• Unique ecological manufacturing process without PVC or softening agents
• High break resistance due to flexible lead
• Simple “12-a-go” refilling for Mars micro, graphite 779 and graphite 760
