HalloweenHow this value is set
Values on this page are community estimates collected from Flee the Facility traders, not official Roblox prices. Frankenstein Brain Jar was last reviewed on 2026-05-22. Demand matters as much as raw value: a high-value item with low demand can sit unsold for weeks, while a mid-tier item with steady demand moves quickly. Always compare both sides of a trade before you accept.
