Funnel webs main function is to create a PVA bag of any size in the shortest time possible - bags can be made in less than 30 seconds, leaving any other system for dust. Funnel Web minimises wasted PVA making it the most cost-effective PVA bag system ever made. If you are not using it in your carp fishing, you're missing out! Once you have used all your PVA you should not throw away your system. Simply buy a Funnel Web refill pack and thread on another 5m or 10m. The refills are available in Hexmesh or Micromesh when you're using tiny baits in 5m or 20m lengths. Each refill is colour coded to match the correct PVA system.
