This is a salt and pepper shaker from KitchenDao, a kitchenware brand known for salt cellars, butter dishes and bottle openers. KitchenDao sells several shaker and salt-box designs, including glass shakers with a side pour spout and wooden salt and pepper boxes with swivel lids, and we could not confirm which design this item is, so material, capacity and size are not listed here. It is used at the table or next to the stove for seasoning food. Please contact us for a photo or details before ordering.
