Ingredible stainless steel/glass grinder set - refillable and adjustable
Model: 2 Pack Salt and Pepper Grinder
Incredible grinder set.
- Unlike some grinders that are made of plastic. This is glass so no reactive, especially to salt. And, no micro-plastic concerns
- You can see inside, so you'll know when you're running low and can shop for more salt or pepper
- Perfect functional size. Some grinders are giant tall towers and other are too small. This one is in the Goldilock zone of just the right size.
- Mill is adjustable and produces a very consistent sized grain.
- EZ to use

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 👍
