The Wolf Moon salt / pepper grinder comes well, amd sensibly packaged.
Unfortunately, it is very small measuring approx 4' height and approx 3/4 inch wide. This would hold very little pepper, just too small for say rock salt, and would need frequent refilling.
It is made from stainless steel and has a clear very small window. It is operated by pushing down on the head of the grinder with the thumb. This forces the pepper out through the blender crushing it very well as the thumb press is pushed. It does sit quite well in the hand and the bottom of the grinder is protected by a stainless steel skirt which is wider and heavier than the top but provides exellent protection.
All in all it is very well made but falls down quite a bit on value for money. It certainly looks much larger than it actually is in the advertising so I find it quite misleading for me.
If, however, you are looking for a smaller device then this would be ok.
Not too good for visually impaired who need a larger, more normal sized grinder. Very expensive and not good value for money unless you require a much smaller grinder, but would still be poor value.
Good for those reducing intake.
