These micro urchin spines have shades of red, green, purple and white. They measure from under 1/8" and the thickness of a hair to 1/2", still slender and delicate.
Each pack contains a gram of them, a scant 1/2 teaspoonful. They are weighed, not counted or measured. There were over 150 pieces in the pack I counted.
Use in sailors valentines, micro shell art and dollhouse shell arrangements.
