The Sipa Sipa footbag (hacky sack) is hand-crocheted in brightly colored rayon thread for durability and high visibility. Sipa Sipa footbags with larger plastic bead filler are fully washable and fun—they produce their own unique sound. The Sipa Sipa was the first hand-crocheted footbag and it was introduced to the world in 1983. The Sipa Sipa is often imitated, but never duplicated. *Color Combinations Will Vary *
