This is being sold as a set but can be bought individually but must buy at least 2 I have the Dulce De Leches Firming boob and belly cream as well as the matching serum. Both only used once. And I have the Cake Maker Tightening butt and leg cream as well as the serum! You can buy both serums, both creams or just the Dulce de leches set or the just the cake maker set or you can buy the whole lot! Please comment or build a bundle and we can talk there!
