The Signature Trolley is the epitome of the iconic LEGO® design and all the nostalgia that surrounds it. In addition to being made of PVC-free material, the Signature Trolley also features silent double wheels, an interior elastic strap, and a zippered mesh pocket for easy organization inside. It comes with a TSA combination lock with 3 digits, silent wheels, and a robust suitcase system. A timeless design that underscores the love for LEGO® bricks. Furthermore, it has the option to expand, providing extra space in the suitcase. When fully expanded, the suitcase can hold 31 liters, and without expanding, it can accommodate 26 liters. If you purchase more than one trolley, they can be stacked on top of each other thanks to the specially designed backside, which also references to the design of a LEGO® brick.
