Summary: Works Great!
Comment: Principally I bought this product because I am a printmaker. Copper Sulphate is one of the ingredients to creating an etching solution for zinc plates.
After ordering the product the delivery was prompt, and I received exactly what I ordered. Also, the product works great. I am very satisfied with my purchase, and will be buying more Copper Sulphate as needed to replenish my zinc plate etching solution.
I also would recommend the seller as they were very prompt in delivering my order.
