This is a set of two books: HOW TO BUILD GUNDAM WORLD 3 "Z GUNDAM" HOW TO BUILD GUNDAM WORLD 4 "GUNDAM ZZ" They were found while cleaning the house. These are Hobby Japan separate volumes dedicated to Gunpla of Mobile Suit Z Gundam and Gundam ZZ. They are quite old, published on May 10, 1986, and December 1, 1986, respectively, but they are in relatively good condition for their age, with no folds or stains. Please check the photos for the Z Gundam book, as the center has come open. The pages are still attached. If sold separately, the Z Gundam book is 2,999 yen, and the Gundam ZZ book is 3,999 yen. Anyone from this generation has probably seen the ZZ Gundam cover at least once, and it still looks incredibly cool even now. In addition, it's full of coolness that you don't see in current Gunpla styles, such as VICDAM. MOBILE SUIT in ACTION ZZ HOBBY JAPAN
