Obsidian Flakes and Spalls


Flat Rate Priority USPS Shipping costs are included in the sale price inside the USA.

SKU: N/A Category:


These boxes of Obsidian flakes and spalls are perfect for making arrowheads, blades and spear points. These are pieces ranging typically from 2 – 6″ long. Obsidian is volcanic glass and it already super heated to no heat treating is necessary. They are ready to knap right out of the box.

Buyers should show extreme caution. Obsidian is EXTREMELY sharp and will absolutely cut you. I do not recommend it for kids for this reason. I recommend hand and eye protection when handling and knapping, and knap in a well ventilated area because of the fine dust particles in creates.
