Here's a free mug I made during my time learning stylized modeling, I tweak the material to fit my liking.
Here's the tutorial if you'd like to learn it too: https://youtu.be/kDzM_QwwNPY by ScribbleMesh
If the video owner deem free download unaccpetable please let me know, I'll take it down immediately.
These mug are everywhere on the internet haha.
