Beautiful reusable glass mouthpieces from Black Leaf®. Simply roll  with an 8mm diameter activated carbon filter or a paper tip and then put it into the mouthpiece.

The sparkling rhinestones add a touch of extravagance while smoking, but also provide due to unevenly smoke paths a little bit cooling of the smoke which is already cleared by the inserted filter. The mouthpiece filters are easy to clean with isopropanol alcohol and warm water.
