Thank you for viewing from among many items. This product uses resin liquid. Small air bubbles may be present. Please understand. These are flower-shaped earrings, about 2cm in size. The decorations are different on the left and right. The one with the butterfly uses slightly more clear resin liquid, giving it a high transparency and a candy-like appearance. The other one uses a bit more colored resin liquid, giving it a more subdued impression. The metal fittings are nickel-free earrings. While they can be used by those with metal allergies, it's not guaranteed to be safe for everyone, so please refrain from purchasing if you are concerned. m(_ _)m I would be encouraged if you like it (⋆ᴗ͈ˬᴗ͈)” I have various other items for sale as well (*^^*) Please take a look when you have time. Please check the profile section for shipping methods, etc. (⋆ᴗ͈ˬᴗ͈)”
