How to flip the Tortoise shell
The Tortoise shell is a members-only Old School RuneScape item — “A word in your shell-like.”. Its Grand Exchange buy limit is 7,500 per 4 hours. Right now it buys at 803 gp and sells at 822 gp — a net margin of 3 gp (0.4% ROI) after the 2% Grand Exchange tax of 16 gp. High alchemy yields 600 gp.
To flip it, place a buy offer near 803 gp and a sell offer near 822 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
