Welcome!  This is an interesting set of two little paper jewelry purchase boxes from Italy probably pre 1950's.  The store info and phone number are on the lids of boxes inside.  Cool little Italian Murano glass collectibles.   The address shows this shop was on a historic street that runs directly along the side of St. Mark's Basilica.  Still a prime location for luxury shops.  The phone number dates them to late 1940's through the 1950's with only 5 digits which confirms mid century.  Since these kinds of items were usually discarded and only the jewelry kept, it is rare to find  them now in such good condition.
