Paper stationery maker "Maruman". You may have seen a sketchbook on the cover that combines orange and black.
Didn't you use it in an art class?
I found this Maruman sketchbook at the 100-yen shop Daiso. Of course, it is sold for 100 yen (excluding tax)!
The size is 122 mm x 174 mm, which is slightly smaller than B6. 18 sheets of text are spelled.
Maruman's sketch book has a smooth texture with irregularities. When you run the colored pencils, the atmospheric texture emerges.
I'm crazy about it with a pleasant drawing taste. It's a mini size so you can use it for sketching on the road or as a stamp book ♪
