The Dynamini is constructed with a brass outer ring and has a knurled aluminum spindle.  It has a ceramic (Si3N4) bearing for it's spin point.  The tops has a brushed finish and the brass will develop a patina over time.  This Dynamini was crafted on a CNC lathe followed by hand finishing and knurling of its stem on a manual lathe.

All Kemner Design tops are designed, crafted and finished in my shop.  I personally test all of he tops for performance prior to shipping them to you.  The Dynamini comes with a personalized owner's card that proudly displays the name of the top, birth date, material and bearing used, serial number and maker's signature.  

Tops can have multiple function; they can be used for stress relief, educational purposes, display or play.  Whatever your choice, this top will provide you with hours of enjoyment.  These solid metal tops are designed to last many lifetimes and can be passed down from generation to generation.

All tops are subject to some flutter/ wobble especially at the end of the spin. This is much more possible with exotic materials like TwisTi and any damascus type metal due to the multiple different materials they are made of. I test spin all my tops and will not allow wobble during the bulk of the spin but there may be some wobble or flutter at the end.
