The One offers a comfortable butterfly shape, a variety of colours to choose from, silicone response, and various skill levels. The best thing about this yo-yo is that it comes with two different bearings. The narrow bearing is perfect for learning the basics of yo-yoing. Swap out the narrow bearing for the upgraded wide-bearing, and the One transforms into a modern performance beast capable of handling the toughest tricks in the game.
