Our sticks are all different diameters, (God makes 'em, we ship 'em), so we never know what size tip to use until we measure the bottom of the stick. To order tips for a stick you own, measure the diameter of the bottom of the stick, about 1/4" from the bottom of the stick. The tips range in size from an INSIDE diameter of 1/2" to 1" in 1/8" increments. Ups Ground or United States Post Office ground shipping only.
