How to flip the Butterfly jar
The Butterfly jar is a members-only Old School RuneScape item — “It's got little holes in the top.”. Its Grand Exchange buy limit is 40 per 4 hours. Right now it buys at 11 gp and sells at 30 gp — a net margin of 19 gp (172.7% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.
To flip it, place a buy offer near 11 gp and a sell offer near 30 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
