I'll answer part of your question - I have the Ciaos - the differences are 1) come in fewer colors 2) can't be used as easily with the Copic Air Brush system 3) hold less 4) are less expensive 5)don't have the number printed on the end of the caps 6) have little holes in the caps so if children swallow them they won't choke (?!?!?!?!?) that's all I can think of. Oh yeah, they are shaped differently - are round like SU markers
Meow is kind of like Aloha. It can mean anything.
