Genkosha has released a coloring book "Mineral and Science Room Coloring Book" that collects designs like natural history specimens. It is an A4 variant and the price is 1,300 yen (excluding tax).
It contains a number of designs such as minerals, specimen boxes, experimental tools, nuts, mushrooms, etc. that have been sketched around the shelves of an old science room. It is organized in items such as natural history notebooks, and when you finish painting all of them, you will have only one picture book in the world.
Also, at the end of the book, there is a method of "mineral coating" that expresses light with colored pencils. You can draw beautifully shining stones from adults to children.
The book was written by Lucica (Kirarasha Satokayoko & Sasaki Satoko), the owner of the shop "Kirarasha" that sells minerals and science hobby goods. Like a mineral lover, he commented, "I want you to transform it into a mineral that is more beautiful than the real thing, and even a fantasy specimen."
