This is the SNAKE BAT from Amazing Gear. It's in good condition as it's been used very little since purchase. Many people are told about the inside-out swing, but most of them are doing it wrong. The true inside-out swing requires using the core, not just the hands. We provide a product that helps you master the true inside-out swing. To increase your distance, you need a swing that uses your core, not just your arms. The SNAKE BAT, which moves freely like a snake, supports the acquisition of a core-driven inside-out swing. It guides you to a "core-driven inside-out" swing, not the incorrect inside-out swing that only uses your arms or the bat from the inside.
