The cork actually is indented into the side of this wine glass and after using it for some wine tasting, the glass is definitely sealed completely inside. The cork is attached somehow to the wine glass so it’s not coming out. The cork is also sealed so there is no harm in washing the wine glass.
You can also save with free shipping on spending over $50!
