A series of high-quality sinking protein balls based on the highest quality natural products, rich in protein, fat and carbohydrates. The approved flavors and additives used in them, as well as the energetic blend of the base, made it possible to obtain an excellent product, which the carp quickly adopted and considered as an easily available, highly nutritious food. They contain a lot of nutrients, flavors and aromas that create a signal that encourages eating in fishing. In this way, they attract carp even from long distances. The high efficiency of the balls has been confirmed in 8 months of testing in stagnant (as well as commercial) and running waters across the country. The quality of the ingredients used in the manufacturing process means that they can compete with much more expensive products.
