"Sonobe-style unit", Unit Origami, 128p

Classic unit origami.  A collection of works centered around the classic unit origami "Sonobe-style unit".
The simplest and most excellent Sonobe unit. No thread or glue is used for assembly. It is easy to fold, but there are certain rules for how to assemble and color. I explained it with illustrations and photos so that people who could not assemble it without knowing it can always make it.

The book is in Japanese, but the illustrations are easy to follow. 128 pages
