Purchased from an official store 3-4 years ago. Immediate purchase is OK. I'm selling it because I don't wear it anymore. No cancellations. It has been stored in a dark place after opening. I will wash it, fold it, and ship it in an OPP bag, etc. I am a non-smoker. I think it's rare because it's not often available.
