A Perfect Gift For Someone Who is Tough To Buy For
Size: 5.3 Inches - 2 Packs with Holder
Very attractive looks and quality build. Most importantly the salt grinder will take sea salt down to powder for popcorn (a make-or-break feature in my house). It doesn't take up much room in the cabinet when stored and very easy to fill. We're just delighted with the value for the money. Any time you are stuck with what to get someone for a birthday, xmas, what ever; you can't go wrong with this Salt & Pepper Grinder Set.

It works but it's not high quality
Size: 5.3 Inches - 1 Pack
Grinder works well except the silver part came loose after using it a couple of times now we have to hold the top part really tight to use it probably should have returned it but it still works

Good Salt Grinder
Size: 5.3 Inches - 1 Pack
Bought this for the pink salt. It crushes it nicely and is easy to fill. The crushing didn't change the taste and this holds a considerable amount of sale. It's a great value for the money and would make a terrific gift.

Works great!
Color: 1 pk
I almost returned this item because, as some others also mentioned, the top is very hard to remove. It needs a little indentation for your finger! But I liked the size and style so I persevered and once you remove it a few times, it eventually comes off easier. This grinder works beautifully. It’s lovely on your table as well as your spice rack. The adjustable grind levels makes it easy to use and I highly recommend this item.

Exactly as I it hoped it to be!

Such a great, little pepper grinder! Works very well and the adjustable grind size is a nice feature. Highly recommend if you need one that doesn't take up too much space.
