You have to adjust them to how course you want your salt and pepper and they are not electric mills
Color: Clear Glass, Size: 2pk, Color: Clear Glass, Size: 2pk
Comes in a set and nicely priced! Seem to be of good quality and they work well. These aren’t battery operated and you control the amount and courseness of the salt and pepper yourself. They look great in any kitchen and they are refillable, which I really like! They have a good ergonomic design to them so they’re easy to handle and operate. The speed of the grinding depends on how you operate it. I really like these and highly recommend them! Great value! 👍
