I've got my Bumble Bag Jessica Messenger Backpack in the Olive Stripe that I'm done with. Excellent used condition...Loved this bag with all my heart!

$15.00 plus shipping. PM me if you are interested.

This is what it looks like - olive with muted coral/rose and teal/blue, a bit of cream, straps and lining are black.
eta: it has one long strap to wear as a messenger and two shorter ones for the backpack; all straps are removable.
