These cat shaped earrings have real sand that was collected from a holiday embedded. They are a reminder of my lovely holiday! Earrings are made with stainless steel posts but can also be custom made with silver posts. Please refer to picture for earring dimensions. Please note: - All earrings are handmade and may not look exactly identical to the pair in picture. - Great care is taken in the making process but small bubbles may be present. Thank you for your understanding. - Please be extra cautious when wearing earrings for the first time and remove if allergic reaction occurs. - Please handle earrings with care as they are delicate. Wearing in water or exposure to extreme conditions is not recommended. Please feel free to contact me if you have any questions.
