● These convenient rubber mats are placed under appliances like washing machines (under the legs) to raise their height by 2.5cm. The product itself is 3cm tall. ● They have been used for a year, so there are some scratches (white areas, not dust), but there is no rubber degradation, and they should function perfectly well as height-adjusting platforms. ● Purchased at a mass retailer for around 2500 yen.
