My favorite pre-roll cone for home filling of joints is the RAW ’98 Special.’
I’ve tried the 1 ¼, King Size and 98 Special sizes of cones. The 98 Special splits the difference between the very large joint of a King Size and the harder to fill, but great for .5 gram to .75 gram sized joints, 1 ¼. You can fill the 98 Special to the same volume as a 1 ¼, however, the length and opening of the 98 Special are much more cooperative.
The 98 Special cones have a taper that gives them a larger opening hole and longer length, making it easier to get ground weed into versus the 1 ¼. The included cardboard shovel is helpful.
The King Size cone is easy to fill but wants to be at least a .7 to 1.25 gram joint.
I am eyeballing my measures based on prior experience and not actually weighing out each joint before filling.
