I took a ride out there yesterday and met with Ron and his wife. He is a very sweet man. We talked for about an hour at his shop/warehouse. I would have to agree, the jars are not as thick as the libby jars. I bought 2 cases of the 8oz metro jars and now that I am really examining them, they dont look exactly the same. But for the price, you can beat it!! They are located in Niles IL.
