Get yourself the Revell scale model kit about 18" long & $30. Glue and paints not include. A true scale model that requires real attention and care unlike Lego blocks.
Totally don't have a clue why supposed adults buy these ugly expense toy blocks. Guess it comes from my building both plastic kits and boats and planes from scratch as a kid. SMH.
Part of the “charm” is that you can disassemble these kits and reassemble them over and over.
No paint skill required
No glue or technical skill required
No artistic skills required
Just patience, attention to detail, gentle hands and a love to build things with your hands
