Love them
Model: 2 Pack Salt and Pepper Grinder
Love those. Good quality material and work very nicely. I like that I could set the size of the ground salt and pepper by myself, this was very useful.

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
