Here’s an original character paper craft model named Kokoto chan.
Kokoto here is designed by Neneha.
To be honest I’m not sure if it’s an original character or taken from a manga / anime.
The designer who makes this seems to be a professional mangaka and has done work in magazine. Try and check their blog if you may.
Kokoto paper craft requires 5 sheets of paper to build and has around 89 parts.
I’d say this model is about medium difficulty in assembling.
If you know what character is this from, do tell me.
