Hi, those are vintage Arthur Umanoff Barstools by Raymor.

Assemblage in Chicago is where we purchased these. If you look up the stools on 1st Dibs you can usually find them. They can vary in price significantly. I've purchased them in the past for as little as $100 per stool...these, however, we paid top market price for b/c of their fantastic condition.

Thank you!

What is the size of the pulls and are they stainless?

Thank you for your question. The hardware is scaled to each cabinet and varies in size. They are in fact stainless steel. Good luck on your project(s) - you can review our full portfolio at nm-interiors.com - Thanks! NMI
