This is a gel-type flotant with a new concept.
Floatant gel in a pen-shaped container is pushed out by clicking the back end of the container to the right rotation and penetrates the delicate brush tip (You don't have to push the tube each time). Application with this brush facilitates selective application (only where you want to float) without over-soaking.
The non-sticky, smooth Floatant gel works well with CDC on hair wings, dry wings, hackle, and any material.
It can also be applied to line, leader, and tippet to reduce drag.
