This is a combination brush carrier and holder. You can keep your brushes inside the container during transport. The top is domed to better guard the brushes from bending; even so try to keep the top of the carrier up if possible so not to put pressure on the tips of the brushes. The brushes come out and go in fast. When you open up the carrier to show half of your brushes, you can hang the carrier on the palette to become a "Brush Holder". This keeps your brushes handy for your use but out of the way at the same time.
