Bronze locks

The Bronze locks is a members-only Old School RuneScape item — “Perhaps someone can do something with this.”. Its Grand Exchange buy limit is 8 per 4 hours. Right now it buys at 20 gp and sells at 1 gp — a net margin of -19 gp (-95.0% ROI) after the 2% Grand Exchange tax. High alchemy yields 480 gp.

To flip it, place a buy offer near 20 gp and a sell offer near 1 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
