Brick-Age x 1 Kit + Old English RedDarkening Extension: Our extension, although well built, always seemed to stand out. We darkened the shade using a blend of your Brick-Age product and your Old English Red at twice the maximum dilution. The result was just as we had hoped! congratulations on such a magnificent product! Best wishes Amanda 2005 Amanda ordered 1x Brick-Age Kit and 1 x Old English Red and 3 extra pots of fixing agent.
