FLOWER SILICONE BOTTLE BRUSH
The point of using this bottle brush is that it is designed to clean something round.
For example, if you need to clean oval bottles that taper at the top around the neck, it is difficult to clean the inside of the bottle.
The brush is made of silicone, so it is elastic and flexible, which allows it to get in through a narrow neck.
While the brush is round, it can clean where other brushes might not be able to clean thoroughly, especially around or under the neck of the bottle.
At the same time, with the tip bristles, cleaning gets easier for every part of the lid, such as swig lids or built tumbler lids.
