Got these thinking they were the slightly larger Panfish floats ru-vid.comUgkx_rJB7cli5f1ofPVGgn80S7Yj4vqwq0gU they work just fine. The smaller size lets me carry more in my tackle box, and the 3 color choices are nice for different lighting conditions, backgrounds, etc. They aren't the most durable things in the world. But, as cheap as they are, it's not heartbreaking to lose one or have to replace a worn one. The price on these fluctuates wildly, from about $9 to almost $16. So, time your buy accordingly.
a nice idea ^^ thanks, I often use porcupine spines as a float, I use nail polish to color them. Like these the porcupine pen is perfect for fish such as chub, trout and barbel and all perch, your "ball" I think will be very interesting for heavy baits such as, bunch of earthworms or corn dough ball
