"SPRUNG" is a completely made-to-order, handmade house brand designed and planned by Sun Optical's Takeuchi Yato, who has traveled around the world as a planning participant alongside METRONOME designer Iwamoto.
Although it is not widely available in Japan, we have now started stocking it at METRONOME-Tokyo. We will continue to add other products as they become available.
(It is not a collection brand, so the products change from time to time.)
