This acrylic reed case is very well-made. It's an older model purchased in 2019, so it doesn't have the humidity adjustment holes (mechanism to let in outside air). The hygrometer displays accurate readings. There are some minor scratches on the surface from use, but there are no issues with functionality such as dirt, damage, or deterioration of the packing. The price of a new one (with humidity adjustment) is 160 euros (29,721 yen).
