Staff of balance

The Staff of balance is a members-only Old School RuneScape item — “A ghastly weapon with evil origins combined with an icon of balance.”. Its Grand Exchange buy limit is effectively unlimited. Right now it buys at 28,821,755 gp and sells at 34,798,999 gp — a net margin of 5,281,265 gp (18.3% ROI) after the 2% Grand Exchange tax of 695,979 gp. High alchemy yields 600,002 gp.

To flip it, place a buy offer near 28,821,755 gp and a sell offer near 34,798,999 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
