Our metal chain and wire is only made of bird-safe stainless steel or nickel-plated steel. NO ZINC. All are sold by the foot. Note: Except for dyed rope, all chain, rope, and wire are shipped as one continuous piece. (If you order 30 feet of wire, we ship it as a 30 foot piece.) If you want them cut down in smaller pieces, please let us know in the comments section of your order. We use a Dremmel Tool to grind down the edges of the wire, otherwise the edges are sharp. Please keep this in mind if you plan on cutting the wire yourself.
