Gakken Mook: Adult Science Magazine Bonus: Small Letterpress Printing Machine Published in 2017 I intended to build it, but I'm not going to, so I'm selling it. As shown in the photos, the book and the box containing the letterpress printing machine materials are separated. The cover, magazine, and bonus box are separate. The contents of the bonus are unopened, but the cellophane tape has deteriorated and is broken. I have not inspected the contents of the bonus. Of course, I haven't assembled it, so I haven't touched the contents, but I cannot be responsible if anyone claims that parts are missing. Please purchase only if you understand this. I intended to build it, so I printed the bonus's fold-out section (how to use it) myself. I'll include it, but it's on the last page of the magazine. Please purchase only if you understand this.
