Seems like it will work fine for the limited stuff I needed.  the end of the pestle that is rounded over is not very well polished at all and I suspect tiny particles of whatever is being ground up or crushed may stain, stick, or discolor it.  The inside of the mortar has grind marks, but seem little smoother like some fine polishing was attempted. 

Pros: small and inexpensive
Cons: perhaps too small and not the finest workmenship
