Pica 4030 Graphite Refill for the Pica Dry® Longlife Automatic Pen is a water soluble “multiuse” lead. The 4030 graphite can be used on almost every surface, no matter if wet or dry, glossy or rough, dusty or oily, and can be wiped clean from glossy surfaces with a damp towel. The Pica 4030 leads come already sharpened and inside a sturdy, reusable plastic box.
