these earrings - pouzettes, are created according to their own graphic processing, then with care and love they are covered with resin for a beautifully shiny surface. The case is made of hypoallergenic steel (surgical stainless steel 316). Dimensions of the cactus width x height x depth approx.: 8x14x1.5 mm. each piece may be slightly different from what you see in the picture, the material is a little unpredictable, but that's what makes them original :-)
