Takayuki Yanase Mechanic Design Works – Amazon Exclusive, Unopened This is an unopened copy of the book sold exclusively on Amazon. A poster is included as a bonus, shrink-wrapped together with the book. I have multiple copies for preservation, but I am selling this one to organize my collection. Since it is shrink-wrapped and unopened, I have not checked the contents, but the exterior condition is good as it has been stored in a dark place. *Please note that due to long-term storage, there may be minor scratches on the shrink wrap or exterior. Please refrain from purchasing if you are looking for a perfect condition item. It will be packaged with cushioning material and measures to prevent water damage, and then shipped via Yu-Packet Post. No need to ask for permission to purchase, and immediate purchase is welcome. Negotiations for price reduction will be declined.
