This is a handcrafted free cup made with care by Tsubame Kobo.

Featuring the calm texture of black clay, a comfortable feel in the hand, the unique glaze resembling overlapping ice crystals, and a dynamic design that transitions from a hexagon to a heptagon—this cup embodies Tsubame Kobo’s three core commitments.

Its versatile size makes it perfect for any drink or use. We hope you’ll enjoy it as a part of your everyday life.

[Commitment to Black Clay]
Tsubame Kobo uses a carefully selected black clay for all its products.
While black clay from Mino is difficult to work with, it offers a unique texture and warmth that other clays cannot replicate.
When you receive your cup, we encourage you to feel the intentionally unglazed parts and appreciate the raw texture of Mino’s black clay—crafted with pride by skilled artisans. It pairs beautifully with sake.

[Commitment to Glaze]
Platinum Blue features a one-of-a-kind brilliance, reminiscent of polished metal.
Because the finish can change depending on temperature and humidity, every Tsubame Kobo piece is crafted by hand rather than by machine, with careful attention paid to the condition of the glaze during production.
The delicate and subtle shifts in color ensure that each cup is truly unique—a one-of-a-kind piece that belongs only to you.

[A Unique Design]
The transformation from a hexagonal base (resembling tortoiseshell) to a heptagonal rim creates a cup that reflects light in complex, shifting ways when filled—producing a one-of-a-kind sparkle with every sip.
The swallow stamp engraved in the unglazed area symbolizes a wish: that, like the swallows returning year after year, you’ll keep coming back to use this cup again and again.

“Not just for special occasions—create special moments in your everyday life.”
That is the sentiment behind Tsubame Kobo’s vessels. We hope they bring beauty to your daily routine.

Beautifully packaged in a box, this piece makes a wonderful gift.
We confidently recommend it as a present for someone special—or as a well-deserved treat for yourself.
