Once only offered on finished flies, Rainy's ever popular PSP popper/diver heads are now available as a tying material! Like our other poppers, these are hand-shaped out of 60# density foam for the highest durability and buoyancy, yet giving flexibility in tying. The foam heads are very unique in shape and optimize popping and diving performance. They are versatile and are designed to be tied in either way creating a big popper or diver. 3 per package.
