北马其顿采购需求：可选产品，不可磨灭的标记

I'm interested in obtaining a sample containing 20% silver nitrate. Could you please provide me with the minimum order quantity for this product? Additionally, I would like to know the pricing details, including shipping costs to Skopje, Macedonia. It would be great if you could also let me know the expected delivery time for this sample. Looking forward to your prompt response so we can proceed with the potential order. Thank you!
