Okay for ceramics
I used these cookie cutters to cut out porcelain ornaments this year. They design is quite nice, but it was super hard to get the clay out with out warping it. The edges were also not as smooth as you would get from the metal cutters. Porcelain clay is easier to work with than cookies doe in my experience, so I would expect that bakers would have similar issues. Pretty, but be prepared for a lot more effort.
