How do you TPFers store your LV bags? I put my bags in the dustbag and then back into the box when I'm not using them, but a SA told me that storing the bag in the box is actually bad for the leather as it will cause it to crack. Has anyone heard this? Is it true that the box will dry out the leather? I'm not sure whether to believe him since he was out of boxes when I bought a bag and if this was just his excuse not to find a box for me.
