Grand Canyon is part of the Caran d’Ache Colours of the Earth series which has since been discontinued. I’ve reviewed Sunset previously which was part of the same series. Grand Canyon is a brown ink which shades nicely. On my TWSBI Mini, it feels super dry but on my Visconti pen it feels lubricated. I feel the experience on my TWSBI Mini is quite bad. It’s like the ultimate worse pairing or something. On the Visconti pen, it is dark, saturated and wet. What a world of difference.
