I (Akari, the owner of kira kira life) have been carrying around a pair of "My Hashi" for the past 15 years (the same one) made by the same artist. Whenever I eat out, I use my own chopsticks, and I love it because not only food tastes better (because I feel at home), but it also saves our natural resources to be used for disposal chopsticks (even if they were made from leftover materials). Unfortunately, the widely used disposal chopsticks are exposed to chemicals that are not good for us and for the earth in the process of making.
You also would look stylish taking out your own "hashi" out of your purse!
