This is a washing machine pan! I bought it for my new home and assembled it, but was told it couldn't be used (by the contractor) right before installation. I disassembled it and stored it unused. I will ship it in this box! The instructions are not included, but are printed on the back! I only assembled it and didn't use it, so if anyone can use it, please do! Purchase price: 3798 yen #washingmachinepan #washingmachinepanwithcasters #slidingtype #washingmachine #newhomepreparation
