So for this achievement you need to buy an item that can be used in both Volta and Pro Clubs
Best way to spot these items is to look at the top left hand corner of the item. If it has both the Pro Clubs and Volta logo
, it is a shareable item.
Alternatively, when you look through the shop, if you press
in certain sections(for example, headwear, facial accessories and tattoos), it will show you which items are the shareable ones.
Best way to do this achievement is to first have 25,000 Volta Coins and then buy any common shareable item. Once you buy and equip it, this achievement will pop.
