Storing paintbrushes has always been a challenge. Storing them tip up encourages water to drip down into the handle and ruin the brush. Storing the horizontally is better, but still not perfect. Ideally, storing them tip down will allow water to drain towards the tip, and will best preserve the life of your brush.
This stand is designed to hold 8 small brushes tip down, and additional 7 spare brushes tip up.
