Yes sir, that is them.
I use the 1" size on a 1/64th trout magnet head.
They can't stand it.
If it swims by a fish, it will get ate.
One note:
The ones in the package like you have, I have found to be much more "fragile" verses the ones that come in the small plastic jar.
I have no idea why but the ones in the jar last longer ????
