Distress Oxide ink
From Craft Wiki
Distress Oxide ink, made by Ranger, is a type of hybrid ink of a combination of dye ink and pigment/chalk ink. This ink reacts with water and is used both for techniques (ink blending or techniques with water) as for stamping.
This ink is only available in full-size square pads, since the formulation of the ink does not work well on smaller ink pads.
Distress Oxide ink is available in 60 colors. Between May 2020 and the end of 2021, 12 new colors will be added to the Distress line.
