The whistles chirp, bark, growl, snort, squawk, quack, grunt, scream, squeak, sing a song in the night, fabulous.
4repack was really cool to work with. They contacted the seller and worked out the weights and everything. They were even hit by hurricane Irma and a Brazillian Postal worker strike and managed to get the whistles here in a reasonable amount of time, by upgrading my shipping and using DHL.
It was a pretty interesting experience just shopping, I kind of assumed that Brazil would have a functional postal service, but not so much. They have a giant river called the Amazon right in the middle of everything. Though more and more I feel like the Amazon is the heart of western culture, from spices and foods to music.
