Each package comes with extra gifts- 10pcs string,1pcs glove,1pcs yoyo pouch.
The N12 is, hands down, the best N-series yo-yo. The simplistic design doesn't hold a candle to the greatnes of the N12. 
The rigid aluminum body allows it to sustain damage, scratches and bumps, but still perform. It's made to allow finger spins and thumb grinds. But it shines the most, when comparing metal finishes, Many team members and reviewers have stated that "The sand blasted finish of the N12 is the best between other yo-yo's in a simmilar price range.". A yo-yo's finish is a staple of true worth, better finishes allow tricks like finger grinds, arm grings, etc., classic competiton grade tricks.
Disclaimer: The N12 comes with a thick ball-bearing, meaning it's unresponsive. Unresponsive yo-yo's require a trick called a bind, to wind up.
