Tone 28 solid toothpaste

This is the Tone 28 product. It is packaged individually like medicine, which is fascinating and convenient for travel. It also significantly reduces the volume.

But it melts and crumbles immediately upon contact with water. The most important thing is to store it properly when not in use. It's really inconvenient to use; if even a single drop of water splashes on it when it's not the right time to use it, it melts and crumbles inside.
