The all new Kannastör® Black Series introduces the first ever monofilament screen to be used in an aluminum grinder.  Monofilament screens are preferred for their higher quality pollen catch.  Volo pioneered the use of monifilament screens in it’s high end RYOT® brand sifting boxes for many years, but until now there has been no way to produce this more desirable screen for an aluminum grinder. After two years of development Volo and Kannastör®  have finally done it..  Each beautifully anodized medical grade Kannastör® Black Series four piece grinder includes both a proprietary EasyChange™ monofilament screen and traditional stainless steel screen so users can experiment with both.  Another great innovation from Volo and Kannastör®.
