Leo's Buttons take the classic coin shell set to an entirely new level. This beautifully crafted set features precision-engineered buttons with a perfectly fitting shell, making it completely invisible. Now, you can perform all your favorite shell routines with ease, and for the first time, Leo Smetsers reveals his full routine and presentation for this unique set. Designed to match the size of dollar coins, these buttons are not only easy to handle but also highly visible, even from a distance!
