Champagne Ring with a 0.4g piece of tungsten in it. This allows to add weight to the rear of the dart. So it is perfect for those seeking to add weight to the back of the dart or for those who feel their darts wobbling in the air or for those who just want to add weight to their dart in general.

Steel tip players who see their darts land with the back high up might notice the biggest difference.
Only meant for use with L-style Champagne flight system.
