Tightly seal and store the unused wire with a desiccant.

Our copper plated steel wire “Mac Wire CP” is rolled with anti-rust paper. You are requested to pay much attention when storing the product.

When there are “Mac Wire CP”s left unused, we recommend you pack and store them in plastic bags with desiccant and volatile discoloration inhibitor.
