Glassblowing pipe

The Glassblowing pipe is a members-only Old School RuneScape item — “Used to form molten glass into useful items.”. Its Grand Exchange buy limit is 40 per 4 hours. Right now it buys at 61 gp and sells at 43 gp — a net margin of -18 gp (-29.5% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.

To flip it, place a buy offer near 61 gp and a sell offer near 43 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
