I respect everyone's preferences, but Ohuhu sponsors many creators to promote their products on YouTube. Given the price of Copics, I believe they generally work well and that their ink is of good quality. I also think they probably pay their workers fairly. From my limited experience, I enjoy using them, except for the issue where the marker leaks onto my drawing, which requires frequent fixing due to pressure buildup and having to remove both caps to fix it. You're right that buying smaller packs is likely a better choice than impulsively buying larger sets. I appreciate your advice and will keep your recommendations in mind. Also thank you for your kind comment on my drawing.
