Funnel for filling powder horns

Today I received a package of 6 small aluminum funnels from Amazon. They are sold for filling small perfume bottles but are a good size for filling a powder horn.

They should also work for filling powder flasks but for those, I prefer the Ted Cash powder flask funnel. The Ted Cash funnel screws into the flask and holds the valve open. It also happens to fit the mouth of a .44-40 case perfectly when I'm handloading.
