Doesn't last
Size: 2.5" x 5.1", Size: 2.5" x 5.1"
This grinder appeared to work great and is one of the few ceramic options available. Unfortunately, the ceramic grinder has already broken inside, detaching from the bottle altogether. There are probably tiny plastic pieces in my leftover peppercorns. Don't buy it unless you want to purchase it every few months, which is unfortunate.

Beautiful and work great
They come not filled which is what I wanted. I filled one with Baja mineral sea salt one with pink sea salt and the other with peppercorns. They are beautiful and work great 👍

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.
