Although designed for a Tombo harmonica, it can hold other manufacturers' and brands' 10-hole harps. I bought this new at a musical instrument store about 7 years ago for fun, but I only used it about 4 or 5 times and have kept it stored at home for a long time. There is some metal discoloration, but the screws and springs are in good working order. I will wipe it down with a disinfectant sheet before shipping it via Nekopos. Please note that the size for Nekopos is tight, so the packaging will be simple. *I am also selling other harps and harmonica holders. I can ship them together, so bulk purchases are welcome.
