This new series of BOOST kendamas are a study of wood. How it looks, plays, and feels. We are using the Splice Series as an opportunity to experiment and test new combinations and styles.

This Splice Series is produced in limited quantities overseas.

The Decade Mod was the first Sweets Kendama to introduce a new shape in years. The extreme playability of this new design meant it had to be brought over into other products we offer. With some tweaks we are proud to offer the BOOST to the world. The BOOST is pretty much a PRIME on steroids.  The cups are slightly bigger, stalls more pronounced, and there is a balance bevel in the bottom cup to make lunars slap with ease.

BOOST tamas are also slightly larger to help improve play and match the bigger cups.
