Nikko Pin Straight Worm White
Nikko Pinworms were designed for Aji fishing in Japan. We don't have Aji in the US, but the pinworms will work nicely for trout, bass and panfish. They are 1.9" long. The Pinworms are scented.
The photo seems to show a gray bottom. That is a shadow. The Pearl White Pinworm is entirely white.
