This is the absolute BEST set of travel chopsticks I've ever owned.
Made in Japan by a professional outdoor equipment company, the product uses durable materials and will certainly last for many years. And they come in a durable pouch with a second set of O-rings. Because they store in a very small space, you can keep them in a pocket for traveling, camping, etc. and also helps you avoid using (and throwing away) plastic utensils.
Though I am a westerner, I have eaten with chopsticks since I was little and prefer them to forks in most dining situations. I purchased the Snow Peak Travel Chopsticks about 8 years ago, but made the mistake of giving them to my (now ex-) girlfriend. She uses them every day and has taken them all over the world, and won't give them them back. So now I purchased another pair for myself and keep them with me at all times. I expect them to last me for the rest of my life, and this time I will never loan them to anyone. ;)
