Dear Sir/Madam, This is SaurabhJain from NL. I'm looking for products with the following specifications: Also it will be great if you can send different metals like stainless steel, copper, zinc alloy, iron etc. (25 each) to start with & to understand quality of each. Later we can increase quantity of these to 1000-2000 pieces per month. Preferred colours can be red, silver, black etc. Ready to pay 20 to 50 cents for one piece depending on the quality. I am attaching some pictures for better understanding. Show More
