The Rod Hutchinson Monster Crab Fluor Pop Up is a very attractive fluorine pop-up for carp fishing. These fluorine pop-ups have a monster crab flavour on a fishmeal base. The pop-ups have a very high buoyancy and are fluorescing under water. These pop-ups can be used as single pop-up, pop-up on top of food and as snowman. Due to the attractive properties, many odours and flavours are released after contact with water.
