18g- 1” Spare O-Rings- Glow- qty. 100

Do you have the tendency to lose the O-rings from your jewelry? Are you looking to add some pep, when you replace them? Our glow O-rings can help in both areas. These rings are sold in bags of 100, so losing one from time to time will no longer be a concern.The rings are available in various sizes, from 18g (1.0mm) through 1" (25mm).  Each ring is made of quality silicone. Because these are made from silicone, the rings should never be heated past 752 degrees F (400 degrees C). These rings run larger, therefore it is suggested to order one size smaller to ensure proper fit. These O-rings are sold and priced per bag of 100.

  • Color: Glow
  • Material: Silicone
  • These run large- order 1 size smaller to ensure proper fit
