The Jilter filters resemble hand filters commonly used for pre-made cigarettes and encourage all smokers who use rolling papers to use a Jilter Tip to reduce the intake of harmful tars and provide the user with a smoother more enjoyable smoke.
Smokers use the cardboard to create a slot to insert the filter which is then inserted into the rolled paper. This double filtration helps eliminate most of the harmful substances and nicotine, but without sacrificing the flavour or aroma.
If used them you can bet that even your dentist will notice. It will help keep you mouth clean and avoids unpleasant throat ulcers after smoking.
