Totally-Tiffany Organization: Sara Buddy Bag The Sara Buddy Bag measures 9″ x 6″ x2″. The bag has one inner tray and a stair step base. The bag was designed for Tri-Blends when using the stair step base. The bag will hold Chameleon markers without the stair step base. Sara holding the Totally-Tiffany Card sized Rotating Design Board. I had to remove the inner tray for this. You could add a few coloring pencils or markers. Sara bag can hold Triblends. I only own two but I believe the bag can hold 24. You can find a Buddy Bag Product grid that lists all the buddy bags along with the measurements and uses of each bag. My YouTube video about the Sara buddy bag.
