Korda Slow Sinking Artificial Boilies, tough plastic imitation baits infused with 3 popular mainline baits flavours. Ideal for resisting the attention of bait robbing crayfish. They can be left out in position with confidence when regular boilies would require regular bait checks and recasting. A recessed cavity on the bore hole allows your bait stop to locate and sit flush for a better more secure presentation.
