8 Kinds of Size Choices: Each sheet includes 8 different sizes of ring size adjusters, ranging from 3 to 10 mm in length. All adjusters are 38 mm in width, with the largest piece measuring approximately 78 x 38 mm. For DIY Use: The largest piece is designed for customization—cut to any shape as needed. Each adjuster is approximately 0.5 mm thick, helping reduce the gap between your ring and finger. If the ring is slightly loose, use half of the adjuster for a secure fit. Product Material: Made from silicone, the adjusters are soft and feature a non-slip adhesive that remains effective through multiple uses until the stickiness gradually wears off. Ring Size Adjuster: Ideal for rings that are slightly too large. These adjusters fit rings with a width greater than 3 mm, providing a snug fit while maintaining an invisible, seamless appearance that does not affect the ring’s visual appeal.
