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 pouch is made of HYPOALLERGENIC steel (Surgical stainless steel 316)
Penguin dimensions  width x height x depth approx.: 8x15x1.5 mm
 
The earrings are waterproof thanks to the resin layer, but do not soak them unnecessarily, so they don't lose their shine.
They will arrive on a cardboard name tag along with silicone size stops and each piece may differ slightly from what you see in the picture, the material is a little unpredictable, but that's what makes them original :-)
