Distance is your Friend
When storing your bags, place each bag upright on the shelf, with a little space between each purse. Beware when bags are stored too close, handles and hardware can leave impressions in the leather of the bag next to it.
WHAT NOT TO DO
Instructions are readily available on the internet, suggesting ironing leather to get the dents out. This method is NOT recommended as a DIY project because the results are more likely to cause additional damage to the leather. The easiest way to prevent this from happening is to store your bags properly.
When storing your bag, keep it stuffed to maintain the shape with tissue paper or bubble wrap.
You can also use items you have on hand, such as a tee-shirt, towel, or pillowcase.
