Unlike silver plate, which can wear off quite quickly, silver-filled will keep its beauty through years of daily wear. Just use the same precautions you would with real silver jewelry - don't expose to harsh chemicals, and when not in use, store in a dry, airtight bag or container. Size: 26 gauge (0.016in, 0.4mm). Round wire, dead soft temper. Quantity: 0.5oz (about 39ft)
