This should work

I made this and it pop

Code:

ItemStack donork = new ItemStack(Material.DIAMOND_BLOCK, 1);
        ItemMeta im = donork.getItemMeta();
        ArrayList<String> idesc1 = new ArrayList<String>();
        if(!donorkit.contains(p.getName())) {
            im.setDisplayName("§3§lPremium kit §c§l(Locked)");
            idesc1.add("§c§lThis is a premium kit!");
            idesc1.add("§c§ldonate at| §6§lnull");
        }else{
            im.setDisplayName("§3§lPremium kit §2§l(Unlocked)");
            idesc1.add("§6§lRight click to activate");
            idesc1.add("§6§lthis kit!");

s up in the inventory, but doesn't have a description or name, it's just a normal diamond block, I removed the if and else statement as a test, but still no luck so it's the itemstack.

Btw § worked on my other itemstacks, so it's not that

Use the ChatColor enum instead of the sign character.

 

john2342 Did you set the donork's ItemMeta to im?

donork.setItemMeta(im);

 

Gerov that just gave me an error

 

john2342 Do you mind say what the error is?
