Prevents "clattering" when carrying! I found a cutlery goods called "a combination set that doesn't make any sound".
A set of chopsticks, a spoon and a chopstick box developed by a skater. The "silicone cushion" on the inside of the chopstick box holds the chopsticks and spoon, making it difficult to make noise when carrying. When I tried shaking the chopstick box lightly, it certainly remained quiet. However, if you shake it strongly, the silicone cushion may not be able to suppress the impact, and there was a slight rattling noise.
It is available on various mail-order sites, and the price range is around 500 to 600 yen. In addition to the "black" introduced this time, there are color variations of "yellow", "green", and "pink". If you often carry your lunch, why not try it?
