White apron

The White apron is a free-to-play Old School RuneScape item — “A mostly clean apron.”. Its Grand Exchange buy limit is 150 per 4 hours. Right now it buys at 37 gp and sells at 45 gp — a net margin of 8 gp (21.6% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.

To flip it, place a buy offer near 37 gp and a sell offer near 45 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
