These would be much more useful if the flag were dyable. Some folks might want them to all be the same color. If I could buy a pack then dye them all the same Jade Dragon green. I would probably but a few packs. But right now I don't find them useful being color locked and at that price.
I suppose you could trade colors with other Avatars (for now) to get all Green? But yes, that is a reasonable request to be able to dye them. Great Idea!
I'm adding additional sets of flags for R122 to my list. This will be easier than setting them up for dying. (so you will be able to buy packs of a single color)
