Details:

For those who prefer a firmer 'push-in' filter-tip, we now have the glass 'Jilter ® Tip' for joints & blunts. In the glass-tip you can optionally insert, up to 2 Jilter® Filters. The glass tip offers another very popular application option: When rolled, protruding, the glass filter-tip, prevents tar from getting close to ones mouth, thus resulting pleasant glass mouthpiece.
