The Pentel EnerGel Document is a rollerball liquid gel pen with pigmented, light-resistant ink. The EnerGel Document ink has been successfully certified to the ISO 27668-2 standard and is therefore specifically intended for use on documents. This makes the EnerGel Document into an essential part of the desk drawer toolkit. The ink is both waterproof and smudge-proof: in outdoor conditions, the ink is weather-resistant and will not bleed or become illegible even in drizzle or on damp paper. The ink also has the important properties of being non-erasable and non-removable, and is also acid-resistant. This makes the rollerball gel pen the tool of choice for applications with specialised requirements – such as archive work.
The original EnerGel ink writes in brilliant colours with excellent contour sharpness, is fast-drying and does not clog up or smear on paper. The elegant, all-black casing on the rollerball liquid gel pen is fitted with a durable metal writing tip and also features a sturdy metal clip as well as a rubberised zone that offers an improved grip while writing. This product is made from 54% recycled materials and, as with most EnerGel pens, is also refillable.
