No problem taking a shower. If you go to the beach to bask in the sun, you'd better put some olive oil on it. You should wear sunscreen anyway. In addition, don't put it with cosmetics when you go home. As for the reason, it's a long story. Hard objects are harmful to amber. Be careful, it's soft! Let's just say it's as hard as your nails. Your nails won't hurt amber, nothing harder than nails! Ha ha! Don't know how to ask me, take care of your amber, you are lucky to get it! This is all fate!
