Dream Galaxy Kyoto Opal (Brush Pen)

This brush pen uses Kyocera's "Kyoto Opal," a synthetic opal, as its barrel.

Natural opal is a precious gemstone alongside sapphire, ruby, and emerald.
The Yume-Ginga, which uses Kyoto Opal developed from the same quartz particles as natural opal, exudes an opalescent effect and offers a refined texture.
*Kyoto Opal is a common name for the synthetic opals, such as colored opals, that Kyocera develops as decorative materials.
