Swim Bait of Castaic

I got lures from Tackle shop, named "Fine Lure" near the big bridge of Lake Biwa .

It is Castaic swim bait.

I saw this lure for the first time in Japan.
There are two kinds, eight and ten inches and they are slow sinking.
It is lures which seem to demonstrate its power in Lake Biwa.
I want to use them early!
Thank you, Mr.Sawai!
