Some things were made for a specific purpose. Other things were made because they are frivolous and fun. The Japanese Wrist-Mounted Finger Piano was created for music lovers who want everything, including their toys, to make beautiful music.
Now everything you touch will become musical gold. Simply slip the wrist band on, put the tips of your fingers into the finger caps, and start jamming away. Instead of only giving you five notes, as that is all your phalanges will allow, you have access to a full octave as there are three extra notes on the wrist band. Pressing on any hard surface will give you a musical note with the option of piano, bells, or cats. I have no idea whatsoever as to why cats might have been included in the musical sounds lineup, but it will make for some interesting music. It does cost $40, but would likely be a better choice than other options that have one-size fits all gloves.
