Use our semi-custom modular bag on it's own or clip it together with your Classic Circa Modular cover.  Customize the inside of your bag with your choices of our POVS's (Pockets Of Various Sizes) 

This is a great stand alone bag but can also provide double duty when combined with the Letter size Modular cover (not included).  Click the Modular Circa System link on your right to see the modular covers for your Circa or Rollabind book. 

A shoulder strap and pad come with this bag.  If you already have one of our shoulder straps just select 'Already Have One' and the cost will be less.
