I am selling these as I didn't end up using them. The size is 52.5mm (thickness) x 800 x 750mm per sheet. Weight is 15kg per sheet. Two sheets are suitable for an upright piano. ※ The listed price is for two sheets, but I have five in total. ※ Please be aware that the cardboard packaging may be dirty. ※ Price negotiations are welcome! ※ I will prioritize the first person to purchase, even during negotiations. If you are interested, please feel free to comment. ♬
