Natural wooden MAHALO ukulele with case. Thank you for viewing. I bought this a few years ago after trying a ukulele workshop, thinking I might continue it as a hobby, but I only used it a few times and it's been stored away for many years. The serial number etc. is visible in the third photo. I don't know anything about adjusting the sound, so the strings do sound, but I haven't made any adjustments at all. The included case has a hole in the top. It's very thin, but I'll include it. Please understand the condition of the sound and the included case before purchasing. Thank you. ^-^
