Every maker should have a quality set of tools for making marks on paper. I’m taking a Design Sketching Class on Instructables and these Copic Sketch Set of 6 Sketching Grey Markers is on the recommended list. I just got my set from Amazon and they are nice. I’ve used Copic Markers for coloring 3D prints and I love them. They are expensive (~$6 each!) but definitely a nice treat. #affiliatelink
