This item is my Nikon AF-S Teleconverter TC-14E III. I’ve switched to Nikon Z so I won’t be usingthis anymore. The TC hasn’t been used amassive amount as I only used it with one lens and often didn’t need the extrareach.
This is as-new, with no marks at all (the photos confirmthis). It’s in its original packaging withaccessories (case, docs etc).
