SevenLeaf's original design for the Pineapple Express strain mixes a ribbon-and-emblem seal inspired by train logos with the tropical spirit of Pineapple Express's Hawaiian strain roots. At the center of the circular seal design is a pineapple, its usual spiky leaves replaced by marijuana leaves, while the PINEAPPLE EXPRESS name is rendered across the center. In keeping with the pineapple theme, the design is printed in green on a yellow t-shirt.
