If you really wanna make this ring sizzle as a trick, buy Kenton Knepper's "The Ring". With this ring, and Kenton's manuscript, you'll have your spectator in a trance before you can say, ummmm. . . ring.
Kenton's original marketed trick came with two rings, so check on the availability of those first. Personally, I can't find the set from Kenton anywhere, so this is a nice add-on.

The ring works as advertised. It appears to zip apart as you rotate the ring one way and zip together as the ring is rotated the other way.

I have the "gold" ring. When brand new it looks beautiful. It sparkles like an 18 karat gold ring. However, you should know that the gold plating wears off. The ring's appearance is not terribly nice as the plating wears off. But wait! There's good news. When the plating is completely gone, the ring looks as though it is made of silver or white gold. I've had people notice it and find it quite interestng. Mine fits my ring-finger and I wear it as my wedding ring.

This is a simple little demonstration. Definitely not going to knock their socks off. The overall quality is okay.

This ring is flashy, kinda small but will fit any pinky guaranteed and I use this for misdirection to people mainly or just like to show people. I recommend buying this because it is really neat and crafted great!

This ring blows. Most of the people in the forum for this ring also says it sucks. Not worth the money, rather get a card trick. DO NOT GET IT!

It's a good trick gets good reactions!!

This trick gets wonderful reactions, and is all around great. This is a must by. Get it now!

This thing's not really magic.. as the title say.. it's just an opticle illusion... and it doesn't look like it shrinks and expands, it looks like it gets fatter and skinier(from the side)...

...it does trip you out. I showed this girl today and she thought it was pretty cool too!

This thing is awesome! Buy it!
