The Sigmas represent the continued evolution of Aroundsquare's begleri range, and the design underscores just how much subtle differences and refinements can affect the feel and play of a set.

The Sigmas feature generously rounded edges, which makes them extremely comfortable to play, and somewhat springy while retaining enough of a "shelf" at the top of the bead stack to make them easy to manipulate. They are very light, and suitable for extended use, but because of the oblong shape, they carry momentum like a heavier set, and feel heavier than the weight would suggest. 

Each bead weighs 3.8g and the set 16.9g including cord. The Natty is machine finished.
