Purple boots

The Purple boots is a free-to-play Old School RuneScape item — “Very stylish!”. Its Grand Exchange buy limit is 150 per 4 hours. Right now it buys at 801 gp and sells at 1,200 gp — a net margin of 375 gp (46.8% ROI) after the 2% Grand Exchange tax of 24 gp. High alchemy yields 300 gp.

To flip it, place a buy offer near 801 gp and a sell offer near 1,200 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
