Boa Backpack - Black There are pockets on the left and right sides, and places where keychains etc. can be attached. I put a pencil and mechanical pencil through them for clarity, but these are not included; only the backpack is. Bottom size: Approximately 27.5cm x 15cm Height: Approximately 40cm Measured by a amateur laying flat, there may be some errors, so please use as a reference. It will be shipped folded, please understand. Thank you for viewing.
