SBS attractors are the life and soul of boilie making. These products cannot be imitated. Results for this product have been outstanding. The completely natural organic water-soluble food source is ideal for the enhancement of the overall impact of boilie mixes and hook baits. This concentrated natural organic formula is best used on its own at the rate of 30ml per 1kg of base mix or with low level flavours. It adds considerable food value to any mix and it is an effective, year-round food source and attractant that catches on even the hardest of waters. The Tonic is an attractant that works perfectly in the coldest of waters.
