NERF Mega XL Dart Refill, Includes 10 Mega XL Whistler Darts, Largest Mega Darts Ever, Makes Whistling Sound When Fired

right fit for this toy.

Its a Mega XL Nerf dart....wouldnt recommend these being shot in a area of the house that has anything delicate/breakable.

Kids love Nerf stuff

Only CON is that there isnt a pack with a higher quantity. Fun to hear them whistle in the air but a bit embarrassing to be hit by them because they should too be easy to dodge.
