RW Leather Belt in Black Tea-Core (Regular Width 1.5")NOTE: ALL BELT BUCKLES ARE MATTE BLACK NOT BRUSHED NICKEL. If you want a black belt that ages like raw denim, go with tea core leather. Its an old school dye process where the hide is first dyed a natural veg tan, then top coated black. Over time, the black wears off to reveal the lighter natural tone underneath building a patina thats earned, not bought. Most brands avoid tea core for its poor colorfastness. We see that as a unique characteristic.
