I purchased this on Amazon and stored it without using it. It has been opened, but it is new. I will ship it in simple packaging. "Space Saving" You can secure space for the drain hose directly under the washing machine! It's also easy to clean and allows for good ventilation. "Vibration Reduction" By using vibration-damping rubber, the vibration and noise from washing can be reduced. "Non-Slip" You can use it with peace of mind because there is a non-slip sheet on the bottom. "Wide Range of Use" It can be used with all manufacturers, so you don't have to worry about the type of waterproof pan. Please note: If using for the legs of a washing machine, there should be no problem with the size. If using for other purposes, please check in advance whether it fits within the dimensions of this product before purchasing.
