Set of 6 Parque Nacional do Iguaçu small mugs Brazil souvenir not used

6 Parque Nacional do Iguaçu small mugs Brought them from my Brazil trip. Ever since stored in clean closet. Never used to drink. Just so many souvenirs and running out of space. They are 6 identical mugs in set. They diameter is about 2 inches and they are a little under 3 inches high. Will come carefully packaged ( I mailed delicate China for 25+ years)
