The Easton Archery Dr. D Vane Primer Pen is a vital tool for arrow building. It's compatible with all vane adhesives, improving the adhesion of stubborn vanes that are typically hard to stick. Not only does it increase bond strength, but it also significantly reduces drying time, allowing you to get back to the hunt faster. As a premium arrow fletching primer, it's an excellent addition to your archery equipment, ensuring your arrows fly straight and true.
