Seiwa's hexagonal intelligent chopsticks. I bought these intending to use them, but my child has passed the target age, so I'm selling them. Chopsticks are quite durable, so I think they can be used from lower grades in elementary school. They are new and unused, but please understand that they have been stored at home. I will include a children's toothbrush as a bonus. I plan to ship them using the cheapest method available.
