These are fluttering attachments to be used with squid jigs. The swivel part is also made strong, which expands the range of customization. When the fluttering attachments are effective, it is possible to use bait or hooks directly, as they are strong. When using, crumple them up for a more effective, scattered reflection. These are leftovers from production, so they are being sold at a bargain price. 20 pieces
