The bottle cap is made of olive wood and is handmade. The unique reddish-brown grain with an irregular fiber pattern on a smooth surface makes the olive wood plugs something exceptional. The bottle cap is ideal for securely sealing bottles. The beautiful bottle caps create a Mediterranean atmosphere on every table. Each item is unique and differs not only in shape/size, but also in grain/color. Clean the unique item with water and, if necessary, a little detergent.
