Convenient bath water pump for washing machines, with a filter. - Product Name: Bath Water Pump Matomete Kirei - Included: Filter, sponge - Usage: Washing machine pump, other pumps can be used - Quantity: 3 uses x 2 + 2 uses x 1 I tried to use it once, but I couldn't figure it out, and it seems the model was different, so I've had it sitting around for over a year. One box is missing one use. Two boxes are unopened. If you use this, or are interested, how about it? Thank you for looking.
