I have 4 of the set in trade and I'm not sure what to ask for them.

Use the {item} tag not url, we can't tell what you are asking us to price.

[*item=*insert item name here] or [*item2=*insert item name here]
( of course remove the asterisks ) - Like so: [item2=Imperial Rose Shoulder Drape]

[item2=Majestic Rose Shoulder Drape]

[item2=Pure Rose Shoulder Drape]

[item2=Royal Rose Shoulder Drape]

You would probably be better off asking here: [Topic=868258]

I would say about 1k Csc and up if I remember correctly
