I had no idea they even made cases for my Otamatone. I have a Mon chichi Otamatone that sat couch side exposed and venerable to pillow attack, children rough play, and misuse. My wife bought this for me as a surprise and we both laughed at how silly a thought it would be to protect my Mon chichi, but in the end this gift brought much happiness. She laughs at how serious I look now on the couch with my encased and guarded Otamatone like I am ready throw on my tux to rush off to a concert at any moment. This is a seriously first chair case and it takes this instrument to the next level.It fits correctly and leaves no room for jostling. The wrist strap would be handy if I ever traveled with mine. I do play, very badly, but at least I know that the potential Otamatone master musician has his instrument are well protected.
