Hey i got a pack of these because i was out of senkos and they look very simialar and the place i was at did not have the real thing.

so my question is do u fish them simialar to a senko?

and do they work well?

They are the exact same bait.  Kinami is Gary Yamamotos son's company the only difference is you get 7 senko's (Flash) instead of 10.

Please read the Senko FAQ.  Kinami's are well covered there.
