Often, when we are working in an apiary it happens to us that when we are in a hurry we can cut our hat/the veil on a sharp edge of something and wham! ... We end up having a broken veil in the hat. The mesh has a hole and the bees can easily enter. In this case, you do not have to buy a new hat, but just the same-mesh veil that obscures the exact damage and will still be able to be used safely.
