well 1 its cheaper than buying the plastic ones. also you don't have to worry about cleaning them just throw them away. none of the ones I made have come unstuck but if the tape unsticks from the paper I doubt it would stick to the snake. I just figured that it was more sanitary than the plastic ones that I used to use. also I don't have access to them unless I order them online.
either way I think they work pretty good and I just thought id let others give it a try.
