This was used for several years to hold small items in my backpack.  I carried a glass repair kit, pain relievers, personal hygiene, etc.  Never used for makeup so no stains on the inside.  Outside has no stains or visible signs of wear.  Stitching does not appear to be perfect on the inside or out but nothing that would stop it from working as designed.  I used it for years the way it was and never had any issue.  Will try to capture it all in the photos but please ask any questions you may have.
