Renegadesignlab (RDL), TriRing? This new prop (2014) is designed by Alessandro Sacchi and now is available in limited quality. The TriRing is used more as an isolation/contact prop similar to an 8 ring and is not intended for toss juggling, or normal ring juggling. Check Alessandro's video to see how it works, https://vimeo.com/59431573 This video is shot with an earlier prototype version, he will have a new video with the new RdL model soon.
The ring is made of 3/16 thick white plastic.
