Schneider Xpress pens produce a nice, bold, richly colored 0.8mm line, and the water based ink is document safe and does not bleed through most papers. It's comfortable to hold and allows the user to write for extended periods of time without tiring, in addition these pens won't dry out even if left uncapped for 2-3 days. The smooth tip is shielded by a stainless steel tube which makes it ideal for using with a ruler, template or other drawing aids and the cap and pocket clip are stylish and durable.
