When it comes to your Blundstone boots you have two main options to care for the leather, pigmented or neutral.
Black and Brown are heavily pigmented cream (50ml) that are designed to help maintain the color and finish of your favorite leather footwear. Always test the product in an inconspicuous area as it may change the appearance of certain leathers.
Rustic Renovating Cream is a neutral-color cream that is suitable for use on full grain or flat leather styles, including Rustic Brown, Rustic Black and Antique Brown. Since this cream is non-pigmented, it can be used on any Blundstone leather boot.
Note: The Rustic Renovating Cream does darken the rustic leathers initially, although the boots keep the 'rustic appearance' and the leather tends to lighten again over time. Always test the product in an inconspicuous area as it may change the appearance of certain leathers.
