Contents: TA06 Aluminum Diff Cover: 1 Assembly Universal Shaft 39mm Swing Shaft: 1 20T/21T AV Pinion: 1 The condition is good, and it is completely unopened. I am selling it at a lower price than new. Discounts are available for bulk purchases, so please feel free to inquire! I also have other radio control car parts for sale, so please take a look!! Although unused, it is a used item, so there may be scratches or scuffs on the box. Please refrain from purchasing if you are sensitive to such details, as it is stored by a private individual. Please check the condition of the item in its entirety in the images. Returns due to customer circumstances, such as overlooking something in the images, are not accepted. If you would like anonymous shipping with tracking, please comment. It will cost more for shipping. I am selling this because my collection has grown too large. I am also selling on other sites, and I will do my best to reflect sales as quickly as possible, but there is a chance that the item may sell on another site first. In that case, the person who purchased it first will be given priority. Thank you for your understanding. If you are concerned about whether the item has been sold, please feel free to comment! ^_^
