This bag fits a ukulele case. I believe I purchased it from the KIWAYA website. The artist, MIYABI HOLOHOLO, may also be found on Instagram. It seems that many backpack-type bags are now being sold. It can hold a hard-case ukulele, sheet music, a music stand, and even a cable. It can be carried over the shoulder, leaving both hands free, which is convenient. Please see the photos for the size. It fits soprano and concert ukuleles. It's very well-made. I used it a few times and have been storing it at home. I'm selling it because I no longer have the opportunity to use it. It will be folded for shipping. Thank you.
