The incredible yo-yo that fits into a business card case has come to America and it's not just a novelty. From the modding mind of world class yo-yo modifier Shinobu comes one of the most drooled over pieces of yo-yo history ever. Every one comes with spinning side caps and a small size A bearing. Every model has small machine marks on each rim. These are not flaws, they are standard on every model and you can consider them a little love from Shinobu himself.
