A bottle brush that is made of natural materials is so much more durable than the synthetic, and even more pleasing to use.
Bottle brush bristle: Twisted wire holds natural bristles and finishes in black bristle tip to wash residue at the bottom of jug, vase or bottle.
Cotton wool top + natural bristle brush: On a wire stem, this hangs after use.
The white wool top at the end gets to the tip vase or bottle and the sides operate like a mini car wash! Made in Germany. Small: 20mm diameter, 13" long
