i wanna give a quick recommendation for this water pen? u can use it to paint with watercolors literally wherever u are and it works super well… like no water cup and towel to clean brushes u just fill it with water and go? also the brush is rly sturdy and u can do a lot of types of lines with it… the one i have is Pentel brand but ive seen other versions from other brands that work the same… i think u can also fill it with ink and paint with ink? anyway i do like 99% of my art with this now and i wanna share the love
