Flli Menegatti Hinged Bangle Candy Apple Red Swirl/Deep Dark Blue Sterling Inlay

Flli Menegatti Hinged Bangle Candy Apple Red Swirl and Deep Deep Dark Blue with Sterling Inlay Stamped 925 and signed Flli Menegatti Made in Italy Closed inside measurement is 2 1/4" at it's widest Weighs 24.90 dwt (pennyweights) Overall condition is excellent with barely any noticeable wear Not being an expert, I am wondering if where the two top ends meet, if there is supposed to be some sort of stem or pin there to secure? A gal friend of mine tried it on, and it was secure as is, just saying. Comes with a gift box, however not the original CJ17
