Another place nickel is found but not routinely considered is in musical instruments.
Metal instruments and their parts/pieces may contain nickel or have nickel plating.
For example, most student-grade model flutes are made with nickel. The higher grade flutes tend to be made of silver which still contains nickel.
To limit exposure to nickel, ask prior to purchasing if the instrument contains nickel, nickel plate, or copper/nickel alloy (brass) in the areas that will be in prolonged contact with the skin. If unsure, test items with Nickel Alert prior to purchase.
Test items that you are in direct contact with for a long period of time. Wash mouthpieces after testing.
Consider testing: Keys, mouthpieces, guitar and cello strings, and tuners.
