i have a filing system dedicated just for my luxury purchases. all paperwork including authenticity cards are organized per set. i also scan these paperwork and file pictures of the items with me wearing them or against a background that is identifiable as mine. i do this as per advice from my insurance broker who told me it's important for any claims if ever something ugly happens. it's work having these items and it makes me even more critical when buying now because of all this documentation involved. sorry i went off tangent but i thought it's kind of related to your question. enjoy your new items. it's so special that you got them from paris.
