Copper Sulfate Small 50lb Bag
Some of our customers have asked for a larger crystal size than our standard mini-crystals---this is the product! Looks like small gravel or 3-5 MM. This is Quimag brand and is shipped in a box and delivered by FedEx. We have a briquette sized copper sulfate if this size is too small for you. Take a look at our Copper Sulfate Large 50lb Bag!
