Flaskborste

Finally got one long enough to actually scrub the bottom of my 24-ounce tumbler without scraping my knuckles. The bristles hold their shape well even after a few aggressive uses, and it dries fast hanging on the hook. My bottles finally smell as clean as they look.

The 14.75-inch length is perfect for reaching the bottom of my tall insulated bottle without scraping my knuckles, and the bristles handle dried coffee residue with zero effort. It’s become the only brush I grab for tumblers too, honestly.

The bristles are firm enough to scrub off dried tea stains but still gentle on the inside of my tumbler. The 14.75-inch length makes it easy to clean the whole bottle without my hand getting stuck, and it's held up well after a few months of daily use.
