This is a green stone death whistle developed and perfected by Master flute maker Xavier Quijas.  This whistle features the lord of the dead in Chalchihuitl stone. Chalchihuitl stones for the ancients were representations of all that is beautiful, life abundant, regenerative, precious,  and of value.  All whistles are crafted by the Master himself,  each is unique in details and voice.  Because this product is hand made, the whistle you receive will not look exactly as it appears on the images. There will be ifferences in coloration size and detail.
