The popular NEXT STARLIGHT has been improved to create the ultimate precision work pieces. High hardness steel balls are pressed into the rotational tip as well as the NEXT CHRONUS. This improves rolling stability and increases driving time dramatically and increases durability. We have passed USA safety standards and sell them simultaneously in Japan. Packaging is English to US specifications. Nexts precision links are made with high precision that does not allow the movement of true roundness or coax to 0.01 mm (1/100 mm) so it will spin on averages over 4 minutes (depending on how you turn it and turn). Developed by Nexto, the monogramming group of Okaya City, Nagano Prefecture. Visit http://seimitsu-koma.jp for more details.
