-offer of Lantern Doctor's Sack + 18 keys = ~2 buds

Sold for Electrostatic Tin Gallon(~1.8/1.7 buds depending on overpay)

Price Talk - Suggested Range: 1.6 - 2 buds

These are the only sales for this hat on outpost within the last month. The high end comes from 2 offers of ~2 buds, while the low end comes from the lowest of the recent sales.
