The Wedding Collection consists of a variety of Shell types that have been hand painted and adorned with a Mr/Mrs. These shells can be used for decor or for the ring bearer to carry rings or on your dresser or nightstand to hold coins, keys, money, rings etc. The XL oyster set is more of a stand alone decor piece that can dress up the bride and groom table or your mantle, bookshelf etc. It's just a conversation piece to celebrate marriage.
