Like a pencil, the Beta Pen has no ink and writes on paper. But unlike your trusty No. 2 pencil, the Beta Pen never needs to be sharpened and never shrinks to an unusable stump. Instead of leaving a trail of graphite on paper, the Beta Pen leaves bits of its metal alloy tip‚Äîso little, in fact, the company says the tip will last nearly forever. The marks it leaves are faint yet permanent. Writing feels like using a particularly hard pencil but without the need to exert much pressure.
