Sweets just keeps making it sweeter.
This is the first time that Sweets put a Boost shaped ken on a $20 model. So before this Kendama, you had to pay at least $50 to get this shape of Ken.
There are two primary shapes of Ken (that is the handle part), the Prime shape and Boost Shape. The Boost shape has bigger cups and the base cup is drilled out to help the balance when doing Lunars.
On top of that they came out with a bunch of colors too. If you have been looking for a great playing Kendama to get started, this is the best deal out there.
