Can someone Explain me this resell logic for Box Scroll and exo?

Can someone explain to me the logic for reselling Perm items you get from boxes, Yeah I know this isn't new or anything... But they're Classified as "Hyper" and they ranged from 20carats to 15k carats. They mention how selling RC to Carats works(the RC item x6) and Selling your carat item you got from the store (i think 25% of its value).

Here are some examples (and yes their all perm):

 

To prevent being full charged. They said.

 

Depends on the box they're obtained from. The developers are to blame for this. They weren't consistent with it.

 

Aside form abyss BFLE got all the rest form the Red Black Friday box (re) : RedLeg BF LE, lightning BF LE , and Zin TKD BF LE

 

Lightning BF LE, Abyss BF LE, and Red Leg BF LE aren’t originally in the Red RE box, so that’s why their resell values are different from the others. They were first introduced in the Blue Black Friday Box.

 

They should change it back! I hate selling only get like 10 or 20 carats!

 

This ruling doesn’t apply to boxed items in store.

Although as Draygashi mentioned, they were never consistent with resell prices of boxed items. My recommendation would to never resell your boxed rares for carats, unless you have a duplicate version of it you want to get rid of.
