20x Bright Silver Filled .925 Round Open Jump Rings 20 Gauge Wire 4mm 20GA

Specifications:

• Materials: 1/10 Silver Filled .925
• Size: 4mm (~0.8mm wire)
• Quantity: 20pcs
• Others: Fine and new finished with clear cut.
• 1/10 Silver-filled, which means that the outer 10% of each item is .925 silver. Silver filled items have a brass core. The silver is mechanically bonded to the brass. Just like Gold Filled items, the result is much thicker than silver plating. This process make the headpins much less expensive than solid sterling silver, and the difference in quality is impossible to see with the naked eye.
• 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  use with real silver jewelry - don't expose to harsh chemicals, and when they are not in use, store in a dry, airtight bag or container.
