ESP 20mm PVA Mesh Kits, ideal for producing Dynamite Sticks and bags and including a Plunger. ESP PVA is produced in their own UK factory offering next level quality and control over the finished product. The bait tube itself has a slightly flared top to make filling easier and is moulded in a tough, durable polymer. The Plunger has a rubberised handle for comfort and is graded in 25mm divisions to help produce uniform size packages and sticks up to 15cm (6") in length.
