Give Legos.

During my childhood, my parents invested a lot in Legos and I still have them after 40+ years in my storage boxes. Easily over 10000 pieces.

I started off with City series up to Technic series. As with Legos, one can dismantle and rebuild into anything.

No need YouTube shit or table rubbish as those will never last.

Legos yes, by another 5 years, my collections would have been 45 years old. Now I gave them to my nieces and nephews to play whenever they drop by for the holidays.
