Dark infinity colour kit

The Dark infinity colour kit is a members-only Old School RuneScape item — “Use on infinity pieces to recolour them!”. Its Grand Exchange buy limit is 4 per 4 hours. Right now it buys at 25,000 gp and sells at 40,925 gp — a net margin of 15,107 gp (60.4% ROI) after the 2% Grand Exchange tax of 818 gp. High alchemy yields 3,000 gp.

To flip it, place a buy offer near 25,000 gp and a sell offer near 40,925 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
