What souvenir can I take home from Brasilia?

I collect souvenirs from different places.

Go to the beach, and collect shells! They're free- and more sentimental than anything 'store bought'!
Have a great time!!!!!!

Depends on what kind of souvenirs you are into.
Im sure you will find replicas of the city麓s weird architecture.
Also the semi precious stones, the area around Brasilia has very rich soil, as far as minerals go.
Cheap too.

Try to get a stuffed piranha (taxidermy).

If you are in Sao Paulo city, go to Praca da Republica. Best place is Embu, about 2 hr drive out of the city.

You can also get semi-precious stones like amethyst, emerald, zircone etc. They make them into small trees. But can be too heavy on your luggage.

Other than that, get anything made from leather like a jacket, gloves, pants or a cap.

I fell in love with a Brazillian from my trip a few weeks ago, though it can be a bit awkward to get in a suitcase.
