These chopsticks are born from a high level of Japanese metal craftsmanship in the city of Sabae in Fukui prefecture, traditionally known for its famous eyeglasses. They are made of titanium alloy and have a superior rigidity to pure titanium that won't transfer heat as much so the tips won't get hot even if you leave them in hot water for long. The tips of the chopsticks are shaped corners so they allow you to pick up small food or noodles easily. They come with their own chopsticks sleeve.
