What is up with Zehtuka's Pack?

How come whenever I see Zehtuka's pack for sale, it's always selling for more than 50k, usually 100k or more. I don't get the attraction, it's identical to a Charr bag, except it's writing is white instead of green, by another name. Nobody but you can see it, same as charr bags, but charr bags should be more valuable due to the fact that they're, well, green. However, they sell for 5-25k, while these packs go for multiple times that cost... I ask you... why? Are these auctions a joke? I always think they are, why would someone pay so much for that bag, when a charr bag is better and cheaper.

I think the idea is is that this is another novelty that you can show off, someone see's you with a crystalline, how can they tell wether some its a horrible purple 1 or a req 7 15% always crystalline, its a rare drop and novelty, people with money tend to spend money on things like this

Yeah, but it's the same thing as a charr bag, in fact, in my opinion a charr bag is better :P
