"Variflex - Precision ABEC-1 Ball Bearing - Gives Incredibly High RPM - Adjustable String Gap - Provides Extra Long Sleeps."
The same company that made this yo-yo also created the Variflex Competition Yo-Yo Kit. This is just the single yo-yo and is identical (except for the bearing) to the Grim Sleeper and the Da Bomb yo-yos made by Team Losi, Inc..
Collected February 11, 1999. At the time this was a very good yo-yo for what you got and the price.
