Bottle Brush (5-Pack)

Wasn't expecting much for the price but these silicone brushes actually scrub without scratching my insulated water bottles. They don't hold onto smells either, which is a big deal after protein shakes. Five in the pack means one lives in the kitchen and one in my gym bag.

Got the 5-pack so I could keep one at work and one by the sink, and the silicone bristles actually reach the bottom corners of my tall water bottles. No weird smell after weeks of daily use, which was my main worry with regular brushes.

The silicone bristles don't scratch my insulated water bottles at all, and they rinse clean without holding onto old smells. Five brushes means I've got one in the kitchen, one by the sink, and spares for the rest.
