Giant egg sac(full)

The Giant egg sac(full) is a members-only Old School RuneScape item — “A giant sac of red spider eggs, hopefully none of them hatch.”. Its Grand Exchange buy limit is 100 per 4 hours. Right now it buys at 17,810 gp and sells at 17,800 gp — a net margin of -366 gp (-2.1% ROI) after the 2% Grand Exchange tax of 356 gp. High alchemy yields 6 gp.
