The Ensso PIUMA has a minimal design with no clip on the cap. The 94 g (3.32 oz) brass edition offered through Massdrop (re-branded as Drop) is a rolling hazard.
The patina - discolouration and stains - from years of contact with the acids, oils and other skin-born substances and air is clearly seen when compared to the product photograph. While my pen is inked with TWSBI black, the Bock nib is painted black, not the unpainted nib pictured in the product photographs.

@septinox Thank you for showing us, but such a relief that it's sold out, as my super heavyweight brass Piuma (which is no longer for sale) would ask too many difficult questions.
