Measuring 12cm to fit from 3 months to 15cm to fit around age 4 or 5, this hypoallergenic, highly polished steel, with rose gold IP baby bracelet has a petite heart charm.  What is gold IP?   "To begin with, a layer of titanium nitride is added to the base surface of stainless steel. Additionally a final plating metal (in this case, rose gold) is added to the surface; the thickness of this layer is no more than 0.3 urn. ... Given its durability and chemical stability, ion plating is rightly called “permanent” coating."

Also available in hypoallergenic steel.
