The color changes with hot water ↔️ ice water. Previously, they would turn a bit whiter when put in hot water (Hayabusa, Komachi, Doctor Yellow), but because they've been played with a lot, some color remains even in hot water. However, the color becomes darker in ice water, so you can enjoy the color change. There are scratches and paint peeling. They have magnets inside, so they stick to walls. Please understand that these are used items before purchasing.
