I've packed this in a lunchbox several times. It's a one-push type chopstick set with a case. It's easier than sliding, so it's safe for young children to carry. It's designed to not make any rattling sounds. There's some slight discoloration on the back of the case. It's the small item shown in the photo. Dishwasher safe.
