Question about PvP Unlocks

I wish to unlock some of the skins for my pvp chars, and i'm wondering if theyre permanent or not.

What i mean is : let's say i pick the skullspear unlock for my default pvp spear. Does this mean after I unlock it, I can create skull spears whenever i want for my pvp spear? Or does it mean i have to pay AGAIN for it to be changed to the skull spear?

You will need to pay every time to change the default PvP Spear into whatever it is you want unfortunently. To make PvP characters look nice your going to have to store different weps in the inventory, when you buy one, save it, because you can just get a new skin put on a PvP default piece.

Same goes for armor.

I only know it for armor but on armor you can make the armor skin whenever you want for that pvp character.

If you delete the pvp character then it's gone.
