▷ Product Silver925 Simple Hoop Earrings ▶︎ Material Silver925 Stamped *The 6mm size has the stamp on the inner side, but it is small and difficult to see. ▷ Size Outer diameter 6mm (thickness 1.5mm) Outer diameter 11mm (thickness 1.5mm) This is a set of 2 earrings. Please let me know your preferred size, 6mm or 11mm, in the comments before purchasing. It's also stylish to wear two different sizes at the same time! *These are hoop earrings where only the post moves, so it may be a little difficult for those who are not used to wearing earrings. Also, there is a risk of damage if pulled strongly. However, the earrings have a clean appearance after wearing and also have the advantage of being difficult to fall out. *Please note that there may be some distortion or minor scratches due to the product being made overseas.
