The watercolour pen set is characterised by its extraordinary packaging, which can be displayed, hung up or set up when flipped open, thus offering practical handling. The hanging hole and support plate are convenient for the presentation in shops, while the box can be flipped open to use, enabling the user to comfortably pick pens. The pens have an oval cross section, which on the one hand prevents them from rolling away and on the other hand provides ergonomic grip.
