I purchased this double-walled Kiriko glass for 9,800 yen on the overseas crowdfunding platform Kickstarter. It's a new concept glass that combines a double-walled glass, which can be held even when hot, with Kiriko glass. It is also microwave-safe. It also has the advantage of being less prone to condensation.
