This is a DOT bag, it is the medium sized, everyday bag that seems to work for most women.  This is the bag I make the most of, by far.  It is 7 inches tall,  10 inches across and 5 inches width.  It has a high quality magnetic strap and a metal frame that overlaps like an old fashioned Doctor's bag.  It is secure and very durable.  It has 38 inch straps.
