Myachi - a fairly new hacky sack-like invention

I have discovered a fairly new hacky sack-like invention that has proven to be very addictive to my friends and I. You mainly play with it on the back of your hands and sometimes with your foot. It is pretty interesting because it fuses martial arts with hacky sack tricks. If you have one, tell me if you like it or not.

Here are two websites about it that I found if you are interested:

looks cool from videos i've seen.

 

Yeah, it's extremely addictive and my friends really want one now.

 

It looks pretty cool, i have been driven to buy one now... i will update you on how i like it.

 

Nice, glad to see someone taking interest. By the way, which Myachi did you buy or are going to buy?
