There are three different sizes of the EVA PVA Mesh Kit available. The smallest two sizes are 20mm and 25mm in diameter respectively. These are both perfect for the angler who likes to target with dynamite sticks, as they enable you to create a long and thin bait sack. The larger size is 32mm in diameter, which is ideal for creating larger, looser, and more rounded bags of bait. All three sizes come with a durable polymer bait tube, which has been designed with a flared top.
