SMOOTH GROOVES. Enjoy velvety rich aromas from the unique combination of the Swiss and HoneyComb percolators. The Swiss perc, named for it's resemblance to Swiss cheese, allows aromas and water pass around the larger holes, filtering and cooling. The HoneyComb perc features a multitude of small holes to further divide (and therefore diffuse) the aromas that pass through. Double the smooth factor with the Swiss HoneyComb. Combo of Precision & Classic size - barrel size of 38mm but same height as Classic. Logo may vary.
