The Fox Bait Bungs ‘Clear’ are transparent stoppers which you use in combination with hair and/or pop-ups. The stopper should first be placed on the hair, then the boilie should be threaded onto it, followed by the end stopper. By using the Bait Bung, the bait can not slide towards the hook and the bait remains on the end of the hair. This keeps the hooking perfect and the chance of losing it is much smaller!
