The art object which enjoys the change of the crystal
I introduce Tempo Drop mini [tempo drop mini] which can enjoy the change of daily crystals from Perrocaliente which always gives fresh surprise.
I do "the storm glass" which Tempo Drop mini is used as a weather prediction caliber at the time of the voyage mainly in Europe in the 19th century, and was in a motif. The practical use as the pre-surveying instrument is difficult in the present age, but please enjoy the state of the crystal changing every day so that scenery changes by a season.
