So I have a problem. I sold someone a Visvim bickle. I originally bought the jacket from Rakuten. I only wore it once or twice for a minimal amount of time. The jacket was perfect when I sold it. However after the guy wore it for a bit the goretex tape started to come off and now the jacket is completely falling apart. He sent it in to get repaired, but supposedly it is not repairable. What do I do?
