This is the Tatsufuto "Ashiage-tai TFi-5505 Washing Machine Height Adjustment Rubber Mat." It raises the height by 45mm. By stacking two, you can adjust the height up to 90mm. Made of extra-thick 100% rubber, it has vibration and soundproofing effects. It can be used for both top-loading and drum-type washing machines. This item has been stored at home. It had become whitish due to the properties of the rubber, so I wiped it down. I've listed it as "Like new." Please understand.
