Bats Blood Ink is a formula that is tied to European grimoires, much like Doves Blood Ink, and the Black Cat Bone. The magician or exorcist, is to take a bat, and pierce it under the left wing, allowing the blood to drain out to make an ink which is exceptional for making pacts in the exorcists Liber Spiritus, or Black Book. Bats Blood Ink formulas show up as novelty products by the early 1900's in America, which was usually just red fountain pen ink. My Bats Blood Ink contains a small amount of powdered bat ash, making this a genuine Bats Blood Ink. Use this ink to mark sigils, contract pacts, make petitions, and use in charms and amulets. Each bottle is hand made, and comes in a 15 ml bottle
