How it works is, you have one paper like ur rolling a normal joint, then you line up the other paper ( or just a thing strip of paper) perpendicular to the first one at the end ur gonna smoke out of, so the edges of the papers line up. The extra paper makes the tip sturdier so u can take bigger, cleaner hits and dont burn ur fingers as easily. I recommend it if ur into joints, but takes some practice. Dont feel like drawing a diagram, sorry.
