⏳ Appreciating

The Pneumatics Add-on Set, while small, has seen significant price appreciation due to its utility in educational settings and Technic builds. As a retired supplemental set, its availability is limited, driving up demand. However, its value is tied to its functionality within larger LEGO systems, making it less appealing to casual collectors. The rising price trend suggests continued appreciation, but potential investors should be aware of the niche market.
