Thank you. I'm planning a follow-up video soon showing my setup for managing it for plein air painting. :) I'm not entirely sure what they are made of - my understanding is they are pure pigment blocks (but what mineral I have no idea, probably depends on colour?). This is what it says on their website: "ArtGraf Tailor Shape is a block of pressed pigment, designed for drawing and painting. Extremely soft and water-soluble ..."
Yeah I've seen people using gloves, but not really practical for outside, I think some sort of case like a watercolour set might be best, or the cork mat from the sets.
