Sandblasted Aluminum Mezuzah cases add a touch of elegance to your doorways. They have clean lines and come in a variety of colors. Brown, bronze and silver are my favorites. The blue-grey did not become popular enough and they don’t make it regularly. I do not have the blue-grey in stock and can’t get it. They are waterproof for outside doors that are not directly in the rain, for example doors that are under an awning, or in a dry climate. Traditional octagon style anodized aluminum mezuzah cases are pictured below the sandblasted cases.
