Ball of cotton has not traded on the Grand Exchange in the last 24 hours. Its official guide price is 230 gp (11 Oct 2026).

The OSRS Wiki has no recorded buy limit for Ball of cotton yet, so Offerbook sizes flips on it by trade volume alone.

High alchemy turns Ball of cotton into 1 gp. Buying one at 230 gp (its guide price, as it has not traded today) and casting with a nature rune at 138 gp costs 368 gp. That is a loss of 367 gp per cast at its guide price, so it is not worth alching for profit right now.
