OXO Good Grips Water Bottle Cleaning Set - Love These!

These are a must have item.  Ever since a friend of my told me about these brushes, and I've found and ordered from Amazon I can't imagine going without them.  I use these everyday to clean my son's sippy cups.  I used the long straw brush to clean the reusable straw that I've stained from drinking tea thru it.
They come in a set of 3 brushes:

Long Bottle Brush: Perfect for cleaning the inside of bottles, even those with narrow necks

Long Straw Brush: Great for getting inside reusable straws , like on sports water bottles or iced coffee tumblers

Detail Cleaner: Ideal for cleaning threads and crevices in caps
