Water-saving washing machine, bath water pump Purchased at Kojima Denki on August 20, 2013. Upon opening, the cord was the built-in type, which was different from what I wanted. I requested a return/exchange, but they refused, stating that they don't accept returns/exchanges once the item has been opened (even though there's a one-year warranty). Therefore, I am listing it for sale. It has only been taken out of the case once and is unused. Thank you.
