Monkey bones

The Monkey bones is a free-to-play Old School RuneScape item — “These are small monkey bones.”. Its Grand Exchange buy limit is 3,000 per 4 hours. Right now it buys at 201 gp and sells at 242 gp — a net margin of 37 gp (18.4% ROI) after the 2% Grand Exchange tax of 4 gp. High alchemy yields 1 gp.

To flip it, place a buy offer near 201 gp and a sell offer near 242 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
