Tiffen makes them.
They can work well and I used them years ago when I used a lot more filters than I do today.
You need to be careful to shade the filters in many shooting situations. The large air space between filters allows sun or even lamp light to get behind the filters and bounce around. Sometimes this only reduces contrast but others it can cause more serious (or interesting depending on your view) problems. If you are already using cheap and/or plastic cameras, I don't think that this is any kind of concern.
