My buddy from the village of Bora Diego, his wife made these. She is pretty talented. They sell them in their shop in Belen. I bought most of my tepi there on this trip, but I did find a few kruripe I liked. I didnt find any kuripe in my journeys that I liked, so these worked out. 
These also have hooks to where you can tie them to a necklace or etc. 
Enjoy
