Hello sorry for my very late answer but when a drop is over I do not check it daily... sorry again. I attach here a pic of the hallmarks we must stamp by the law. Please check and compare with ones on your pens. I'm 100% sure that what you see are them. Note: these stamps are compulsory (we must put them) and are released from our goverment since we are silversmith and enrolled into Italian jewelry register. Their function is to guarantee the customers that the metal is really silver 925, besides there is a number that identifies us as silversmiths. Not dents so but an added value to the pen since truly made of silver. I hope that you find this information usefull and if you have any follow up questions plese do not hesitate to rech back out to me. Best regards from Italy. Maurizio
