This is the full size version of the Inkless Pen and a top seller. Great gift for artists, designers or doodlers. It allows them to sketch without needing to constantly sharpen the point. It is always ready, never dry, never dull. This Bauhaus inspired design will fast become your GO TO PEN in your pen cup when function must be guaranteed in that moment of fleeting thoughts. The pens can be used on most paper surfaces, at any temperature or in any weather condition and will never need to be sharpened. There is no ink, so it will never dry up or leak. Doesn't smear.
