Purchased at a warehouse store for Polish pottery in the Netherlands. Likely not available in Japan. A Polish Pottery tea strainer with a ball. The tea ball is large, making it useful for brewing a generous amount of tea. I think I used it once, but it's in very clean condition. - Type: Tea strainer - Material: Stainless steel, ceramic - Design: Floral ceramic ball - Size: Approximately 6.5cm (outer diameter) - Use: For extracting tea leaves Thank you for looking.
