How to use
Use the Rystor CK-01 on clean, dry drafting paper or comparable media. Hold the pen at a comfortable angle and apply light, steady pressure to achieve uniform lines. For precise measurements or guidelines, use rulers or templates to guide the nib. Replace the cap after use to prevent the tip from drying out. If line density appears uneven, test on a scrap area to confirm surface compatibility.
Usage recommendations
Store horizontally or with the cap securely closed to preserve ink quality. Avoid using on highly absorbent or textured papers that may increase bleeding; for archival documents, verify ink permanence on a test sample before final use.
