While all spiders have venom, not all are considered medically significant in humans. Purple spiders, like in our Origami Purple Spider cursor pack, are not dangerous to humans, though a bite can cause pain, swelling, redness, and urticating hairs on some purple tarantulas might cause significant skin irritation. And that's about alive Avicularia purpurea, also known as purple tree tarantula, but we have the one made from folding paper in an old Japanese art style.
