The material is zinc alloy. The size of the can is approximately 0.8 x 3mm. It has a lovely Margaret motif with Epo and a design on one side. The small size allows you to combine it with your favorite charm or use it as a focal point. Since the back is flat, you can attach 3mm round plate metal fittings. *As this is an accessory, the color may change to reflect changes in fashion. Also, during the processing process, color shading may occur without prior notice. Please note. (Some parts may differ in color from other parts.)
