We recommend purchasing and wearing the Nerf Rival mask when using the Nerf Rival blasters for safety reasons. The foam balls really don't hurt if you get hit, so feel free to fire away on friends as long as you take the proper safety precautions.
We also think you'll want to buy more foam balls to prolong the Nerf battle because we went through all 12 of ours very quickly.
