These are from about 20 years ago. They were only played with on the plane and are in near-new condition, having been stored for a long time. However, some parts are damaged from storage. Photo 8: Some parts have likely melted due to temperature differences, but they are usable. Photo 9: Some parts have likely melted due to temperature differences, and they are unusable.

If you are considering purchasing, please also take a look at my profile. There is no outer box. They will be sent compactly via Yu-Packet Post. They are expected to mix during transport, but they have been packed as shown in photo 11. Photo 12 shows the tentative packaging. Basically, I plan to tape this and only provide waterproof protection. If you have any preferences for the shipping method, please comment before purchasing.
