MagicYoYo K1 is a beginner yoyo by MagicYoYo.
It features hubstacks and a slightly larger than normal diameter and has a concave shape to more easily hold and catch it.
The outer rim has a matte/coarse finish while the rest is smooth, this is presumably done to aid grinds, like another well known hubstacked plastic yoyo.
The body is made from polycarbonate plastic.
It's uses a C sized bearing (YYJ size). The string gap is slightly smaller than most higher end yoyo's, this makes this particular yoyo good for both responsive and unresponsive play, depending on the lubrication and the state of the response pads.
