Worker Mod Stefans come in Green, White and Yellow in a box of 50. Worker Mod Stefan short darts have a rubber tip and a firm foam body. These darts can improve the accuracy and range of your blaster! We recommend using the matching Worker Mod Magazine. Some blasters are unable to fire Stefans in their stock form. This is most likely due to an air restrictor peg which must be removed before Stefans can be used.
