“Edamame” Bottle Cleaners

Drop these two weighted sponges into your sports bottle, baby bottle, or carafe with a little bit of soap and water and shake for 30 seconds or more (depending on how dirty the item is) to help scrub the hard-to-reach places. Instructions are included with each pair of bean sponges. Suitable for bottle openings larger than 0.8″ diameter. Made in Japan.
