Thank you for viewing. This is a book that allows you to create a pendulum clock using papercraft. The parts are printed on thick paper, and by cutting them out and assembling them, you can create a working pendulum clock. It's an English book, and there's a little bit of instructions at the end, but most of it is explained with diagrams. I bought it intending to try it, but I never used it and have been storing it. The staples have been removed, but all the pages are present. Someone, please complete it! It's a foreign book, and the price is about $19. That's about 3000 yen. A practical book filled with blueprints for making paper clocks. - Title: Make Your Own Working Paper Clock - Author: James Smith Rudolph - Foreword: Isaac Asimov - Contents: Blueprints for paper clocks - Number of blueprints: Numerous parts diagrams - How to make it: Cut out and assemble Thank you for viewing.
