The Ultimate Baits Fluo Pop Ups are pop-up boilies in bright fluorescent colors that stand out underwater. Because of this strong visual stimulus, the boilies will be noticed sooner, which increases the chance of a bite. You can offer the Fluo Pop Ups as a single bait but you can also use them as a snowman using a bottom bait and a pop up. The boilies come in resealable 50 gram jars in the mixed sizes of 12 and 15 mm. Multiple aromas available.
