This is Attack ZERO specifically for drum-type washing machines. I received it as a bonus when I bought the washing machine, but it doesn't suit my family's preference for scent, so I'm selling it. The 5 refill packs are unopened. The bottle has been opened, but it's filled up to around the "refill to here" line. (As shown in the second photo, but it's quite difficult to see due to the bottle design) On Amazon, it's around 1 yen per 1ml, but I'm selling it at 1 yen per 3ml. Please refrain from purchasing if you are sensitive to items stored by a non-professional.
