Created with American milled aircraft grade aluminium, the Space Case Large Titanium Grinder is built to last and is also anodized for increased strength. The outer edge contains centering wedges so your herbs are pushed back to the centre for constant movement whilst the bi-directional diamond teeth do their job until your optimum texture is achieved. At 3.5 inches wide, and just under 3 inches tall, this is a serious sized grinder. The Space Case Large Titanium Grinder is a must-have for anyone who wants their herbs grinded to a superior quality, with the added bonus of durability, strength and precision.
