Got this so I didn’t have to use a dollar bill and a lighter to accomplish the same goal. This does work well but i chose to return it and I’ll tell you why.It makes the material used super soft and powdery. Which might sound great, but if you’re trying to have that same material be absorbed in the nasal area. It just doesn’t have the same “cut” or sharp edges that doing it other ways would have. So while I might have increased surface area, smaller particles, and all of the powder just glides off it leaving none except the tiniest amount on the tool. It just doesn’t work as well.
