These are called Piperoids; they are fun little guys that came in paper tubes that you cut up and create little people out of. They were Christmas presents I got this year and they were a lot of fun to make.
There are three different guys (and their pets/friends) here:
Guyzer and Bean
Rokusuke and Hatchi
Tengking and Tsubuten
And! Once you make them they don’t just sit there and gather dust, they can become your memo holders ;D
