Matze Koch Pop-Ups MK Adventure Booster Balls (coconut/hemp) Let the pop-up float 5-10 cm above the ground. For longer leaders, determine the hovering height with coarse lead or kneaded lead. Also try the snowman. A Monstercrab Robin Red Boilie followed by a Pop up makes a super catchy double lure that will stand out on a feeding carpet. You will find 15 mm as well as 20 mm boilie balls in the glass, so you can always be flexible. No matter if a 20 er, two 15 er or a snowman, from a 20 er basic boilie and a 15 er pop up, you have all possibilities. Content: 75 g.
