I have an opportunity to buy a pre-owned but almost new condition, rarely used K35 Sellier mou in Indigo blue in chèvre. I have read here that sellier mous are rare, and in the coveted chèvre leather, too! It's a no-brainer, right? I also prefer 35s with my Birkins and Kellys. I think I just need some enabling. Haha. Your thoughts, please.
