Price not negotiable!! Brand new, unused knob removed from a product, as a bonus. It can be used directly on the imz 100, but I'm not sure about other manufacturers! Please check the images as there may be initial minor scratches due to being a foreign product!! Please do not purchase if you are looking for perfection or are overly concerned about details!! No returns or refunds to prevent swapping! No cancellations or returns for personal reasons!! To those who purchase, please be sure to rate on the day of arrival!! I will block those who ignore comments!! I will re-check the operation before shipping. Drag sound present! Those in remote islands or those who take a long time to rate, please do not purchase!! ⚠️Recently, there have been too many people who cannot be contacted after purchase or who do not rate even after delivery, so I will give a negative rating for any reason to those who rate after the day of delivery⚠️ I will cancel the transaction if someone from a remote island purchases!! Also, I will immediately block those who negotiate the price without considering the shipping and handling fees!! I will block and refuse transactions from those with negative ratings, depending on the reason, to avoid trouble!!
