pininfarinaSpace inkless pen, pure grey, NPKRE01654

I was so exited to recibe this pen, I am a pen fanatic being of Italian design and all - unfortunately it just looks good but it doesn't really right in an easy nor legible way - disappointed- I travel and should have return it just ran out of time :(

It is nice, the design is really beautiful but to be honest it is complicated to find the occasion tu use it, in the regular paper writes really weak, you can barely see it, so if you need to take notes in a regular notebook, this is not for you. I don’t feel the relation between cost-benefit, for what you paid, you can do something else

bel regalo , penna di gran stile . regalo molto apprezzato

Lo compre para hacer un regalo a un amigo. Le ha gustado. El envío lo recibí en el tiempo establecido y en la forma prevista. Todo perfecto.

特定の紙（コピー用紙など）には鉛筆の様にスラスラと書ける。安い紙には薄くしか書けない。よって全ての紙に印字出来る訳では無さそうです。説明書通りに紙を摩擦によって酸化させてペン先を錆させその錆で印字する。酸化しにくい紙には反応が薄いと思われる。しかしながら、この発明と発想は素晴らしいと思う。総合評価としては高額なおもちゃ。いや、考え様によってはコピー用紙にデッサンするなら一生使える鉛筆！安いのかも？
