1. Lego's own design. The designer's initial creation, approval and production are all complicated processes, which will definitely cost money.

2. The quality of Lego is good. The plastic quality of those domestic manufacturers who imitate Lego is really poor. It not only smells (toxic), but also cuts your hand when assembling the handle.

Lego has to pay the copyright fee. For example, Disney series, Star Wars series and Marvel comic DC series all need to be paid. This is to respect the fruits of other people's labor and respect the law. I really don't understand why so many people defend plagiarized domestic products.
