A. Temma Kiriko, Edo Kiriko, and Satsuma Kiriko originate from different regions (Osaka, Tokyo, and Kagoshima, respetively) of Japan, each with its own distinctive cutting style.

Temma Kiriko's signature is its oval cuts, made with U-shaped wheels for a softer brilliance and a smoother feel in the hand. In contrast, Edo Kiriko is known for its sharp V-shaped cuts, while Satsuma Kiriko features deep carving into thick glass with a gradient effect (bokashi).

One of Temma Kiriko's most distinctive features is the kaleidoscope-like reflections created when liquid is poured into the glass. Light reflects the pattern on the base onto the inner walls, bringing the design to life.

A. All Temma Kiriko glasses are handcrafted at Atelier RAU, the Temma Kiriko atelier in Osaka, Japan.

A few tips:

• Do not use a dishwasher, as it can damage the glass
