Ok will try that. Thank you so much! You put my crazy mind at ease ☺️Date codes does not matter. The bag could just have been lying in a storage room for a while. I recently rammed a door hard into my tote bag leather strap, and it looked really bad. But I massaged and bent it for a few minutes and the creases went away.
Normal use of the bag will also take care of creases after a while.
