Silica sand is a type of sand that is produced when refining ceramic clay. It is generally mixed with mortar or concrete and widely used on construction sites. Doi and Nagaya sought to discover new value in this material and created these ingenious incense holder stones.

Inspired by the incense burners found at Buddhist altars, incense sticks are inserted directly into the silica sand stones, allowing the stick to burn and drop its ash onto the stones. With one quick shake of the jar, the ash falls to the bottom, creating an effortless cleanup between sticks.

Each set of silica sand stones comes in a glass KINTO dish, ready for immediate use.
