You should forget the past that use paper clips or pins to clamp the files if you have the more high-leveler and reusable stuff that Designer Agustin Otegui called it “Tenso”. Tenso uses of two shells that has a row of “Bayonet lock” on the edge combined with the fan-shaped structure.
According to the thickness of the paper manually adjust its firmness- just set it up to suitable region with your fingers. The merits of this is obvious, it provide a larger contact area, more stronger then the ordinary paper clip or pin for clamping something and more beautiful. The important is that Tenso is reusable!
