Kuretake Bimoji Cambio
Bimoji pens from Kuretake in Japan are traditional Japanese brushes in modern marker form.
These bristle-type brush tip pens are filled with water-based pigment ink.
The new "Cambio" series features a continuous ink flow system with a solid barrel that doesn't require squeezing to release ink. Plus, when the ink runs out, the barrel cartridges are replaceable!
