NERF Mega XL Whistling Refill Darts

Brand new, unopened pack of 10. Never been used. In their original unopened package. When you're ready to make your Nerf battles bigger than ever, gear up with Nerf Mega XL blasters, featuring the largest Nerf Mega darts ever! And when these monster-sized Nerf Mega XL foam darts fly through the air, they make a whistling sound. The competition will see and hear them coming -- and will know that you're in this battle to win big. This refill pack includes 10 Official Nerf Mega XL whistler darts. Eyewear recommended (not included). Blasters each sold separately. These are each almost 6 inches long! To be clear, these do not come with the toy blasters. ONLY the whistling darts. I'm currently on a trade break so all my items are for sale only.
