F5 Pop-Ups Super buoyant baits with double flavour & attractor level. F5 pop-ups are produced in 14mm, 16mm and 20mm. All of our pop-ups come with high quality containers & also include a ‘dipping basket’. The dipping basket allows you to drop the quantity of boilies required into the liquid dip enabling you to totally cover & submerge them – no more dropping them into the pot & having to go in with your fingers!
