These are real stingray barbs 1 to 3 inches long and rather sharp at the tip! Tips can be easily blunted using course sandpaper or other abrasives. Barbs consist of dentine and enamel which is basically the same thing that teeth are made out of. There is some minor variation in shape between various barbs. These barbs are also equipped with tiny angled smaller spines as seen in the 3rd photo. The smaller spines are not sharp but they will tend to snag on fuzzy objects. The smaller spines make it so that the spine only wants to travel in one direction. Because of this trait, sting ray barbs have been used by many native populations throughout the world for things like arrow heads, spears, fishing hooks, needles, awls, and artwork. Photos are stock photos showing typical barbs. Foreign customers, my apologies but US export law does not allow me to ship wild animal products out of country.
