The Santa Cruz 4 piece grinder is an ultra high quality grinder.This grinder/shredder/sifter is made from ultrasonically cleansed anodized aluminum, providing unparalleled wear and scratch resistance. A very strong magnet will insure that your herbs won't fall out or dry up, and the special “knurled” grip design will make using and rotating the grinder much easier. But the best part of the Santa Cruz herb grinder is it"s innovative teeth design. The grinder teeth are extremely strong, cut both ways and actually provide “Fluff To Perfection” as the manufacturer promises. The Sant Cruz comes in three sizes - 1.6, 2.1 and 2.75 inches in diameter- and five different colors.
