Sigma TC-1401 teleconverter for Canon

I am Selling a Sigma TC-1401 teleconverter for Canon. I’ve only used it three times over the past two years, so it’s technically like new. I bought it in the summer of 2022 at Scandinavian Photo. It works perfectly, but I’m selling it because I don’t use it enough. You will receive it with the original lens caps, lens holder, and box, as shown in the picture.
