Libro para colorear: Shapeshift
'Shapeshift - An Adult & Children’s Coloring Book' is an adult coloring book AND a children's coloring book combined. It is specially designed to connect parents (or grandparents) with their kids to spend more time together, in an increasingly distracted world. They are running a Kickstarter campaign now that is ending on the 26th of July, 2018. You can get a copy of their book here.
