DIFFUSER Premium Series is handcrafted by highly skilled artisans in Japan. The leather used for this series is sourced from luxurious soft calf skin. Only around 30 pieces of this rare leather strap can be obtained from a single premium calfskin hide. The metal fittings are made from coated sterling silver, adding a touch of elegance.

Following the coating process, craftsmen undertake intricate handiwork in decorative caulking, adjusting the clearance meticulously to ensure a perfect fit. Each piece is unique work of art.
