Ink roller with warning light at the end of the pen which lights up when pressed too hard. The child thus learns to use the pen in a relaxed manner. Shaky and cramping hands, fatigue and lack of concentration are substantially reduced. The writing pressure learned corresponds approximately to the necessary writing pressure to write properly with a fountain pen. The Base Senso is thus ideal preparation for learning dynamic and clean handwriting with the fountain pen. It has a young writers grip piece with three anti-slip rubber finger areas and writes with a replaceable roller cartridge 881 with erasable royal blue ink. Each cartridge has a new stable writing tip made of stainless steel.
