Mexican skulls are handmade. No two pieces are exactly the same. They have a stainless steel earring so they don't give you allergies and they weigh absolutely nothing, so they're very comfortable to wear and put on with anything. All our designs are pieces created by hand in an artisanal way, being unique pieces from limited editions, unrepeatable and unique, that you won't find the same in other stores. Disem is your accessories store, if you are looking to wear exclusive and different jewelry with a fun and cheerful touch. Approximate measurements: 3 x 2cm with earring included. Care: Take care not to put the earrings in contact with perfumes or other cleaning liquids that could damage them. Clean with mild soap and water if necessary and they have a lot of dirt. If not, with a slightly damp cloth, this is usually sufficient. It is not recommended to bathe with them in salt water because over time they could deteriorate.
