Clip Tuner Brand new, unused item. 440Hz Suitable for guitar, bass, violin, ukulele, etc. Includes the included battery + 1 extra, so you can rest assured even if the battery runs out. Effectively 450 yen if you consider buying from a 100-yen shop! Although it's unused, I will open it once and test its operation with my own batteries before shipping, so please purchase with confidence. Please note that shipping will be in simple packaging to keep the price low. Also, the box will be disassembled and included in the package.
