The minimalist design of this gel pen deliberately embeds the clip in the body to maintain the impression that it is all of one single piece. The ink refill cartridge, which is located inside the precisely manufactured aluminium body, can be used simply by twisting it. The matt surface of the pen radiates quality, is pleasant to the touch and eliminates irritating light reflection. The pen, which is comfortable to hold, gets its name from the cross section of the body in the shape of a water drop.
