BaliYo products are truly groundbreaking. BaliYo designs take their inspiration from butterfly knives, which are well known for the tricks their carriers perform with them. Unlike butterfly knives, which are proscribed in many places throughout the world, a BaliYo is an expertly weighted pen with perfect symmetry and weight ratios capable of performing amazing spins, flips, and twirls. Rugged in construction with stainless pivot rings and clips and incorporating a functional pen, a BaliYo is your ticket to hours of enjoyment learning great spins, flips and more.
