At Exegol Outpost, we do mystery boxes a bit differently. Choose a level for your mystery box, and we send you enough parts to create FOUR different sabers, built in whatever fashion you prefer. Our Xenopixel Mystery box includes 1 Xenopixel core and 3 smooth swing cores, and our basic mystery box includes 2 eco cores and 2 smoothswing cores. Any way you slice it (pun intended), no mystery box out there gives you the option for 4 sabers in one kit. We hope you enjoy!
