Second-hand LEGO®
Secondhand LEGO® is ideal if you want to build more with the same budget, or if you're looking for sets and parts you don't find everywhere anymore. You can use them to expand a city, complete a MOC, or simply enjoy building again without having to buy new everything.
A major advantage of LEGO® is that the system has been compatible for decades. The LEGO Group states that the design of the LEGO brick has been consistent since 1958, meaning bricks from the past still fit with bricks from today. This makes buying used LEGO® extra attractive: you can combine older and newer pieces without any hassle.
