TH [SEP] These work great, just like any 'thai deoderant crystal', same stuff. They are a little 'rough' at first,  a use or two makes them smooth. You get 3+ pieces to make the weight,  packed in a box. So all in all a good deal if this method works for you! Also, since you're getting a few pieces, you won't be caught short when it inevitably smacks the tile bathroom floor and shatters 😅
