I am interested in your magnetic hematite rings. Are these 6mm dome shape? Could you land them here in the US for the $190 per 1000 price?. I do not need displays if that would make a difference. What is the size range? Please give me a quote landed by air frieght to my address: NSC Wholesale 826 River Ave SE #26 Roanoke, VA 24013 Thank you A J
