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 farThis.  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.  The straps on this bag are 28 inches.  
 
It is hard to show the lining but it is the cutest piece of kids in costumes from different countries.
