This handcrafted free cup by Tsubame Kobo showcases the brand’s commitment to traditional craftsmanship.
Featuring a calming texture created from black Mino clay, a refined blue metallic glaze reminiscent of aged silver, and a dynamic shape that transitions from a hexagonal base to a heptagonal rim, this piece embodies Tsubame Kobo’s three core values.
Its versatile size makes it perfect for any beverage—an ideal companion for your everyday moments.
[Commitment to Black Clay]
Tsubame Kobo uses carefully selected black clay from Mino, known for its unique warmth and texture.
Though challenging to handle, it creates surfaces and finishes that other clays cannot achieve.
When you receive your cup, we encourage you to touch the unglazed sections, left bare on purpose, to experience the raw beauty of the clay and the artisan’s dedication. Enjoy the texture alongside your favorite drink.
[Commitment to Glaze – Metallic]
The metallic glaze evokes the beauty of weathered silver and aged metal.
Because the finish can vary depending on temperature and humidity, each cup is created individually with great care.
These subtle variations in color and texture make every piece completely unique—truly your own personal cup.
[A Special Design]
The transition from a hexagonal base (tortoiseshell pattern) to a heptagonal rim creates a visually dynamic form.
When filled, light reflects and refracts in unpredictable ways, giving off a fleeting brilliance with each sip.
The swallow stamp carved into the unglazed section symbolizes a wish—that like a swallow returning each year, you’ll want to use this cup again and again.
“Not just for special occasions, but to create special moments in your daily life.”
That’s the spirit behind Tsubame Kobo’s sakeware. We hope it brings a touch of beauty and thoughtfulness to your everyday routine.
Gift-boxed, this piece also makes a beautiful present.
Whether as a heartfelt gift or a personal reward, we confidently recommend it as a timeless and cherished item.
*Due to manufacturing reasons, there may be uneven glaze or streak-like patterns.
