Hello! (●´ω｀●) Thank you for viewing my product. This is a Pentax 2x converter. I purchased it on Mercari a few years ago, but I ended up never using it and have been storing it. Please refrain from purchasing if you are looking for a perfect item or are very particular, as it is a home-stored item by an amateur. ※ Everything in the images is included. ※ There are no smokers in my family. ※ I do not have any pets. ※ Immediate purchase and price negotiations are welcome. ※ I would appreciate it if you could send me a message after the transaction is completed. ※ Basically, I will ship anonymously via Rakuraku Mercari, but it may be changed to Yu-Yu Mercari depending on the package size. ※ I may reuse cardboard boxes from Amazon, etc. ※ I intend to sell only items that can be used unless otherwise stated as defective or junk, but please feel free to comment if you have any concerns. --------------------AI Text-------------------- [High Magnification Expandability] This PENTAX rear converter provides a 2x magnification, effectively extending the focal length of your lens.
