Ishimaru Color Bar's Hot Buttered Rum ink captures the magic of the pousse-café technique—layered liqueurs creating visual depth. Add water to this rich brown ink and watch it transform into a stunning rainbow of colors: blue, yellow, pink, green, and more. The ink shifts from deep brown to a lovely reddish hue, delivering a dynamic writing experience that changes with every drop. A Japanese-crafted ink for collectors who appreciate color complexity and visual surprise.
