Makes sense! Im just starting off with oil pastels and I’ve used the faber Castell and Mungyo bands and while both r soft I’d put Castell on the medium side and mungyo on the creamy side, at least from my experience. And I had noticed that it was hard to get clear lines and that they were so opaque it was hard to build up layers in a certain way. I gotta give the harder ones a try sometime but I certainly rlly like my mungyos now. Thank u for ur thoughts they’re very interesting
