ACR30W MF SSK I don't know the symbol on the headrest itself, but this is the vehicle identification number. ❤️ Estima ☆ Headrest It's been over 10 years, but this is a headrest for the rear seats of an Estima. I received it with a cover (when I bought the car new) I didn't need it, so I never installed it and it's been stored at home. #It's new and unused, but it's an old model, so I wonder if there's a demand for it? If that's okay with you, please consider it. ☆d(^-^)。☆ ※The shipping method may be changed. Please understand. d(^-^)。☆ Compatible car manufacturer...Toyota
