Finally, I found a chopstick holder!! I can't believe how difficult it was to find this simple plastic chopstick holder that is covered. I can find bamboo types or any cups to hold chopsticks, but those all aren't covered so dust falls onto them and into the holder.
I've been searching for one for a couple of years now. I even asked my friend who is Japanese and lives in Japan to find me one. He had no idea what I was talking about. I told him I know we used to have one about 30 years ago so there must be such a thing. He still had no idea. So I thought maybe in recent years they may have phased out. He is a bit younger than I am.
Anyway, the Marukai 99 Cents Store had this chopstick holder for about $8. I didn't see it right away and just happed to see it when we were about to leave. I was so excited and immediately grabbed it.
