Does anyone use a leather conditioner on their bags? I'd like to keep the leather of my paddington as soft as possible. I'd also like to use it on the handles and leather accents of my vintage Speedy when I get it to keep it in good condition. What do you all use? I just read a thread on the eBay handbag forum about not using mink oil. Someone suggested Leather Therapy or Lexall. Any tips and suggestions would be wonderful!
