I had this as a spare for my Downy ball, but I'm selling it because I can't use it anymore since I replaced my washing machine. The lid pops open with centrifugal force (the sound is cute!), releasing the fabric softener inside onto the clothes. *Please note that there may be some scratches due to home storage. Please purchase only if you understand this. ◎How to use ・Cannot be used with drum-type washing machines. ・Put the fabric softener in the dispenser and place it on top of the clothes before starting the automatic washing machine. ・The hook will come off during the spin cycle before rinsing, due to the centrifugal force of the washing machine, and the fabric softener inside will come out in appropriate amounts and spread over the laundry. ・The fabric softener is more effective when set to one rinse.
