This is the powerful female version of the death whistle. It was believed by the ancients that women who died in childbirth shall recieve the title of Cihuateotl ( god/divine/sacre woman) in honor of their sacrifice. Their bones were considered to be powerful and sacred. Images and amulets representing them were considered to empower the owner or wearer with fierceness and courage, hence warriors would carry these to the battle ground. These whistles are craftend in the same ancient tradition of the Cihuateteoh. All whistles are crafted by the Master himself,  each is unique in details and voice. The basic measurements are 4x4x3x3.  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.
