They are a BOE item from Naxxramus. It’s very nice to give non-raiding people at least an opportunity to pick up some epic items, and give the raiding folk an opportunity to make a bit of cash. They sure are an upgrade from the only green quest item she was still wearing . Bought a +hit / + ap gem for it for only 20g.

Prices of gems have dropped quite a bit lately, so if you haven’t visited the ah lately (at least on EU-Aggramar), you might want to check out whether there are any cheap upgrades available.
