Grinder Set of 3
I really like these I use one for rainbow peppercorns and one for black peppercorns. The third one I am using for some coarse pink salt I accidently purchased instead of fine, once the coarse salt is used up, I plan to use it for white peppercorns. They work great, look good and are the perfect size for everyday use.

Poor Quality
I wouldn't gift these... they seem to start having grinding issues after a few days of use. It feels like the grinding piece is binding / going to break when turning the top. Would not purchase again, and look for more durable item.
