Review on Silicone Bottle Brush Multi-Pack: 3 Brushes + 1 Sponge - Effortlessly Clean Narrow Neck Containers, Vases, and Glassware by Ashley Jones

I was looking for a silicone brush that could clean the "hose" of my humidifier. The diameter of this tube is slightly larger than the neck of a wine bottle. The nipple brush was the only brush that fit in this tube. Unfortunately, the handle wasn't long enough to reach the ground. If this pen was as long as the other pens, it would be perfect. So overall I gave it 4 stars. They seem very durable. I don't need the supplied silicone pad. I love that I can put these brushes in the dishwasher to clean them.
