## Questions & Answers

**Q: Can double check if it comes with the strainer and towel?**
A: It does come with a strainer.

**Q: is it dark b;ack or more of a dark, charcoal?**
A: Black. It is a great sink, easy to clean and holding up to kids.

**Q: Our counter top hole size is 31x20. Is this feasible?**
A: The hole in my counter for this sink as an undermount is 28.5x18.5". I think your 31" dimension would be too big, even if the sink were drop-in mounted.

**Q: Is the color shiny black or matte black?**
A: Thanks for your inquiry. 

Our Granite inks are matte black.

Looks nice, cleans up easy, doesn't chip, has a deep drain screener to catch debris, if you have hard water like we do, the spots easily come off easy with a spray calcium-lime remover. Quality item - glad we bought.
