Some of our brushes come with a storage box to keep your brush moist between strokes, such as our Platinum Precision or Platinum Angled Facade Brush. Otherwise, you can use a plastic bag, for example, and seal it tightly around the brush to keep air out. This keeps the brush moist until the next day. Once you’ve finished using your brush, you can clean it and reuse it until the next time, read more in our article: caring for and cleaning your brush.
