@Splig I tried brush pen (pentel type, but a old one, maybe I have to find a more precise one) and fountain pen and I was like "Nope! I can't operate this way" 😆 But I miss a bit of thickness to my lines and generosity. I never tried Zebra pen, maybe a brand that is not implemented well in France; a lot of Bic, Reynolds, Pentel, Stabilo, Staedler, Faber Castle here. I'll try to purchase one and try it ( oh, I checked them online: ink gel, cool).
