قلم طراحی — Staedtler Lumocolor Permanent

توضیحات

A genuine Staedtler Lumocolor permanent fine-tip pen, hand-picked for the Plotterpix. The water-resistant pigment ink dries in seconds, lays down crisp archival-quality lines on paper, and resists smudging — exactly what you want when the bot is drawing portraits one after another. Refillable, light-fast, and dry-safe (cap left off for days without drying out), it is the workhorse pen we use in production.
