About this Product
16 mm / .625 inch blowgun cones. The hole is slightly conical, 3 mm (.118 inch) to 2.4 mm (.094 inch), for a tight fit.
Before you use the cone, first remove the excess plastic powder from the hole with a sharp object (example: the sharp end of a dart). The last bit of powder can be blown out through the hole in the back of the cone. The hole seals when you put the shaft in place.
The cones weigh about 0.53 gram or 0.018 ounce.
