Sulphur Wicks- Where Do I Buy?

[Wernerherzog]

My club and I have been storing our barrels with a citric acid/SO2 solution, but I read that this leeches flavor from the wood. I want to use sulphur wicks but haven't found them anywhere online or in local Homebrew shops. Can anyone direct me?

I think you can also mix up the same solution with K-meta.
