Practical, smart and environmentally friendly - the Feed GP4 has it all! The innovative design allows four ink colours (Black, Blue, Red, Green) in one pen. The pen's ergonomic base and rubber grip provide a great writing experience. The Feed GP4 is part of Pilot's BeGreen range and is produced from recycled plastic.By manufacturing a Feed GP4 Ballpoint pen from recycled plastic, Pilot reduces the carbon footprint of the pen compared to the same pen made from non-recycled plastic. But it doesn't stop there, refilling the pen at least three times will reduce carbon emissions even further. From manufacture, to the end of the product's life, it is estimated that by purchasing this Begreen pen, and then refilling it three times, you reduce the pen's overall environmental impact by -80%** compared to buying three more new pens instead. A small gesture can make a big difference in the fight against climate change!The blue ink in this pen and its refill are certified by the Swedish Archives.
