Metal parts

Also appears on labels as: copper metal bell, zinc alloy hardware, abs-coated d-rings

Rings, clips, buckles and bells made of metal, such as iron, copper or zinc alloy, sometimes coated in plastic.

Watched ingredients get highlighted on every product panel you open.

Where it comes from
Cast, stamped or machined.
Why it's in the product
Hardware that takes the load, or a bell that rings.
Safety and toxicity
Small parts are a swallowing hazard, and a swallowed part made of zinc or a zinc alloy releases zinc, which is toxic. Worn hardware on a collar or leash is a different exposure from a bell inside a toy.
