Additional Details ------------------------------ Product description: Speed Stacks Pro Series 2x are designed for stackers who dream of world records! Based on our super-popular PS2 Clears, PS2x sets are printed only on the top step, resulting in a fresh, clean-hand feel with the authenticity of genuine Speed Stacks gear. PS2x cups are fully endorsed by the World Sport Stacking Association for use in WSSA competition.

Shorties are an exciting new, lightning fast mid-size cup. While still big enough to grip with the whole hand, their shorter height means they can be stacked much faster, so expect record times with these cups (no, they cannot be used in competition yet, but a new category may be created in the future). Younger stackers will also welcome Shorties because they are easier to hold with smaller hands. Even more exciting is that Shorties come with 15 cups in each set, which opens up a whole new world of stacking patterns! Shorties are a Pro Series 2 style, open top cup, and come with a Shorties Stem that securely holds all 15 cups. The inaugural edition of Shorties are white with charcoal step printing to reduce printing wear.

Speed Stacks are the only cups permitted for use in WSSA sanctioned events and each Speed Stacks cup carries the official WSSA approval mark. Speed Stacks, Inc. is the worldwide leader in Sport Stacking (formerly known as Cup Stacking). Sport Stacking is an amazing sport of fitness, agility, concentration and quickness.
