Absolutely essential if you want to take part in the pellet revolution. These bands are perfect for hooking small and medium sized pellets. There's a complicated picture on the back of the pack showing how to use them if you're fishing for "proper" carp. For the rest of us, simply put the band over the pellet, then slip the hook either under the band, or hook it if your eyes are good enough !!. There are plenty of times when the pellet will outfish every other bait on match carp waters. If pellet is allowed on your water, then you MUST have a pack of these bands. Pack contains at least 100 bands.
