weapon mtx for 2x 2h maces question Verdant Weapon

I want to purchase a weapon skin for a 2h mace. I wield 2x 2h maces. Do I need to purchase this skin twice? That's completely ridiculous if the answer is yes. lmk please before I go and waste money spending 40$ so I can change the mtx on 2 maces. 20$ for a weapon mtx is pretty steep, now I need to pay twice?!

Will I be able to use the "Verdant Weapon" shop mtx purchase on both of my 2h maces that I wield? I feel like I'm going to buy the cosmetic and it won't even work. If I can use the verdant weapon transmog on both of the 2h maces I wield (I run giants blood) I'd like to know. If I can't then I don't want to purchase it.
