Red and green resin charms. These are irregularly shaped resin charms. The color test for eyes... I think it was this combination, right? I think there were even these colors on the clear sheets used for studying for exams. I wanted to say it was like the initial Pokémon colors, but they're actually quite subdued in color. The metal fittings are attached, but the wire used for hanging is just for the photo^^; Size is about 1 centimeter. Suitable for earrings, etc.
