How to flip the Black nails
The Black nails is a members-only Old School RuneScape item — “Keeps things in place fairly permanently.”. Its Grand Exchange buy limit is 13,000 per 4 hours. Right now it buys at 1,600 gp and sells at 1,650 gp — a net margin of 17 gp (1.1% ROI) after the 2% Grand Exchange tax of 33 gp. High alchemy yields 7 gp.
To flip it, place a buy offer near 1,600 gp and a sell offer near 1,650 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
