The next evolution of the Envy series is the NVx. This version takes the radical H shape that the Envy is known for and smooths it out to offer a more contoured feeling but it keeps with the original H shape design with an extreme balance of weight on its rims which result in great spin times. It uses a size D shieldless bearing and the HSpin Custom Silicone stickers for the response system. Plus these yo-yos look very unique, you will no doubt be the envy of all your friends.
