My main Clip Studio Paint brushes. They are mostly modifications of default tools, so don't expect anything extraordinary. But this is what I use to work, 99% of the time.
Edit 2021.12.27: updated the set with my latest additions and tweaks to the set, which now contains 14 brushes.
Edit 2022.08.30: updated the set with a few tweaks. The set now contains 16 unique brushes
To import them in CSP just drag and drop the files into the brushes panel. Please let me know if you have any feedback for this product at firstname.lastname@example.org, I'll be happy to improve it in the future.
