MVP's last mystery box of the season and it’s only partly a mystery. We’re excited to be offering the Mostly Electron, Mostly Mystery Box! This box has 9 — mostly Electron —  Lab Second discs inside, with a chance of other plastics, like R2 Neutron, making surprise appearances. In addition, we put the next great experiment from MVP R&D inside — a Prototype Eclipse Electron Envy will be in every box! Reminder, these are prototypes so variance in glow time is to be expected, but — mostly — expect an incredible disc!
