THis bag is 18 inchches across or a foot and half which is more than enough room for any makeup / jewelry that you will be taking traveling with.  There is a zipper compartment that will hold your jewelery.  When you unzip the bag your makeup will be flat and easy to sop.  Also the bag is able to contain any breakage such as as a broken fingernail polish.  Would like to see small compartments to keep the brushes in one place.  My one major complaint is that when you zip up the bag you are left with a really long cord which is easy to snag on things but the cord shrinks down when the bag is opened.
