Fishing jewelery FDR Glider is designed especially for lovers of feeder fishing. Thanks to this small detail you can make the assembly with continuous attachment of the feeder. Pull the thread or the cord through the center of the black plastic olive. The hole is 1.5mm wide, so you can comfortably pull thicker threads or cords through. On the plastic bead there is a swivel and a snap hook into which you can easily attach any feeder. The package contains 5 pieces.
