Bags inserts specially made and advertised for Hermes bags. Bags are meant to be used. I understand we all want to take good care of our bags but these bag inserts can take up up to 20% of bag space. Keys or objects with sharp edges or corners can be placed in a soft pouch. Bags lined in chèvre and swift are ok! Despite heavy regular usage the inside of my bags have not disintegrated. There may be some unavoidable scratches at the base but they are unnoticeable and quite easily smoothed away. I’ve even seen bag inserts for mini Kellys - with that insert in I don’t know what little meaningful use is left out of that tiny bag.
