  • UNIQUE DESIGN: The large rounded corners of the stainless steel sink undermount make cleaning easier. It can be wiped to every corner of the sink without making it hide dirt, thus keeping the stainless steel kitchen sink clean and beautiful.

  • NOISE REDUCTION AND ANTI-CONDENSATION: The kitchen sink undermount is covered with extra thick non-toxic sound-absorbing pads to absorb vibrations and reduce noise, creating a quiet kitchen work environment. The anti-condensation coating on the stainless steel sink can effectively prevent condensation from damaging the cabinet and also increase the life of the kitchen sink.

  • Not a true matte black, but still pretty
Style: 15x15Inch Color: Black
Sink is beautiful but be aware color is not really matte black. More like a dark grey/black. I bought a matte black faucet to go with it, and the sink coordinates, but isa lighter sheen and color.
