... I really have no clue which is the right category for a mug I've customized with a fanart OTL. Cuz it's not like I've modeled the cup, so I'm not sure it belongs to Artisans and Crafts.
My personal mug, now with Moogles drawn by yours truly. On those pics you can't see, but there is also my name written on it.
There are pens with special inks that don't go with the water when you wash it, but you have to "bake" the mug in an oven in order to fix the ink. I use this mug at work everyday
