A handy 2-piece brush kit to keep your bottle and its associated small parts clean like a Swiss clock.

Don't be fooled into thinking this is just for one brand of bottles. The large brush fits through a 25 mm (1") bottle mouth with ease and reaches the bottom of rather deep containers. The smaller one is great for cleaning mouthpieces, nozzles, and such. It has an external diameter of 16 mm and fits through 6 mm holes with ease. (0.63" and 0.25" respectively.)
