I've been trying to slowly move away from Copics even though I've spent so much on them the last decade I never really realized how bad at archival proofing they are.
Been using some Winsor & Newton Watercolor markers since they're pigment and archival quality and while I've always been afraid of traditional watercolors these make it easier because of the marker familiarity. Just wish they weren't so dang picky what paper you can use em on but oh well guess that's the trade off. Definitely have been fun to use though!
