How to flip the Brass key
The Brass key is a free-to-play Old School RuneScape item — “Opens a door that leads into a dungeon.”. Its Grand Exchange buy limit is 15 per 4 hours. Right now it buys at 481 gp and sells at 490 gp — a net margin of 0 gp (0.0% ROI) after the 2% Grand Exchange tax of 9 gp. High alchemy yields 1 gp.
To flip it, place a buy offer near 481 gp and a sell offer near 490 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
