No is not!!!
Have you tried both? Because the leather dye barely stained a rosewood board I tested on and the stew mac one covered in the 1st try!
Well i can tell you i just ordered some from them a few weeks ago, and its Fiebings professional oil dye

And its nothing but leather dye you can clearly see from the pic. the horse saddle on it. On the side of the bottle it tells its leather dye and the instructions for its use on brown leather.
