Beautifully weighted and smooth. It comes in a zip-up black case for great storage.
Rotate in your hand, roll between your palms or roll to massage are three great ways you can use them. To gain an idea of how they feel to use - if you have some fat textas on hand place two in the same hand, side by side, and rotate around themselves.
Some like to put the metallic ones in the fridge between uses.
The 305 gm is super weighted and both a great stim product but also fabulous as a weighted product. The most common comment we hear when people try it is "ahhhh" & "this is so satisfying"
