What product do you use on your rm bags? I have the desire, which I think is lamb, And the care card says a protectant is recommended but what? I have apple, but will that be enough? Should I use apple spray? A different brand? A cream? A spray?? I'm so confused! I don't want to ruin my bag, or darken the leather accidentally. Please tell me what you use on your bag, and what bag/leather it is!
