Store description excerpt
This is an application for playing messages of HEART KNIFE's kitchen knife. If you hold your smartphone's camera over the sound waveform engraved on the knife, you can play back the recorded sound. You can listen to messages from the sender with one smartphone at any time any where, so you can always feel close to your important one. You can also create an original kitchen knife with a message like the one you received, so easily send the joy you felt when you received a kitchen knife to the person who is important to you.
