With no level restriction I see this as being a good twink item, as far as i can tell there is no restriction on equiping or the effects on it I haven't tested this theory as I have all level 70 characters but farm this lots and even the 70s like it as a range easy to come by. I think the pricing on here is extremely low though for what the item is. I sell them for around the 40k mark 45k in baz and 30-35 for fast sales or to guildies.
Have had a guildy shouting in /gu that these have rotted by the dozen for her due to commonality and LORE ... she had at LEAST 5 rot while I was on in 6 hours or so, maybe more.
