From Slusny:
The newest release from Berry, the Unicorn. Robert Kucera Zdenek Hybl who stands behind the name Berry, put together their experience of competition to create an incredibly stable yoyo. The Unicorn, has a slightly larger diameter than the classic yo-yo, and in conjunction with the already mentioned stability in terms of yoyo that will spin for a long time after you make all your combos.
Barely Legal is a Czech company that makes yoyos always in limited number and it is uncertain when or even if these yoyos will ever again be available.
