You get both! They are both factory sealed!!! The packs in each should be 1x Evolving Skies and 1x Sword & Shield Base. So that means you will get 2x Evolving Skies packs and 2x Sword & Shield Base packs. (May also get Sun & Moon instead of Sword & Shield, but always has Evolving Skies). Rare item from Pokemon 25 Anniversary. Get it while you can. Selling at a great price. Each pack also contains 3 oversized cards.
