Angler's paint

The Angler's paint is a members-only Old School RuneScape item — “A salmon pink paint. This might look good on a boat.”. Its Grand Exchange buy limit is effectively unlimited. Right now it buys at 9,000,000 gp and sells at 9,359,997 gp — a net margin of 172,798 gp (1.9% ROI) after the 2% Grand Exchange tax of 187,199 gp. High alchemy yields 1 gp.

To flip it, place a buy offer near 9,000,000 gp and a sell offer near 9,359,997 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
