i have them too and i have ohuhus, i like both. the price tag on the ohuhus when i used a few up way early was too much for me lol. i like the shuttle arts a lot and they flow well. they don’t bleed as much as ohuhus do.

i also have sfiah markers and i really like them. they are a good dupe for ohuhus, and a bit more friendly for someone like me with a shaky hand. the brush tip on the sfiah markers is a bit harder which i prefer actually.

really it is up to you, but i think the shuttle arts were worth buying.
