Dear Customer, Thanks for your inquiry. As for the frame#SJ5365M, this is made of
Metal which usually contains nickel but it is the most widely used material to make eyeglass frames. Many people opt for metal frames because they are attractive and for their malleability and resistance to corrosion. If you have nickel allergy, we recommend choosing TR which is referred to as plastic titanium. TR frames are lightweight and resistant to impacts and high temperature. It comes in a range of colors and won't release any chemical residues. Please refer to this
