Great quality perfect finish for the custom drs for my latest project

These are nice and heavy and seem quite well made for the money. About a third of the price of an Emtek Stuttgart lever, which looks very similar, and is made of solid forged brass. I wish Emtek would describe the materials and construction used for these less-expensive pieces branded "Expressions by Emtek." Are they solid metal? Zinc? Etc. Regardless, I would purchase these again because they appear to be very good value.
