Thank you for viewing. This is the Canon MOUNT ADAPTER EF-EOS M. I received it from the manufacturer when I purchased the EOS M6 in 2017. I have not taken it outside the house, and I do not smoke. It has been stored in the original box it came in from the manufacturer for a long time, and I have attached and detached it about twice to check its operation and condition. Both the exterior and interior are in beautiful condition (※ based on a layman's assessment). I have another adapter of the same type, so this is a surplus item. ※ Please note that a tripod mount is not originally included. The product contents are as shown in the photos: Mount adapter (without tripod mount), front cap, rear cap, instruction manual, outer box. Although it has been used very little, it is still a used item. No claims and no returns, and please refrain from purchasing if you are particularly concerned about the condition. In addition, it will be cleaned with a simple alcohol wipe, and will be shipped using the original packaging materials from the manufacturer.
