This Craft Sha Silver Pen is a practical leathercraft tool designed to mark clean, visible lines on chrome tanned leather. Its precise ballpoint tip produces a thin silver trace ideal for cutting guides, stitch lines, and hole positioning without tearing or scratching the leather surface. The pen includes a cap to protect the tip when not in use.It is particularly useful for chrome tanned leather, which does not accept traditional stylus or scratch-based marking tools. The silver line contrasts well against dark or glossy leather, making it easy to follow when punching holes, cutting curves, or aligning stitching. Also suitable for use on synthetic leathers or where visibility is critical.Product Data:• Pen Type: Ballpoint-style marking pen• Line Colour: Silver• Tip: Fine metal tip• Body: Transparent barrel with gold internal shaft• Includes: Protective blue cap• Country of Origin: JapanTo use, uncap the pen and press lightly against the leather surface to draw your desired guide lines. The ink will appear as a silver mark and is most effective on darker chrome tanned surfaces. Avoid pressing too hard to prevent overmarking. Recap after each use to prevent drying.Store the pen in a cool, dry place with the cap firmly in place. Do not leave exposed to air for extended periods to maintain ink fluidity.
