Louis XVI used this wallet for his secret correspondence with Beaumarchais and used to contain papers which contents the King did not want the court to know about. The wallet is made of red Moroccan leather decorated with golden motifs. The inside is lined with green silk. It is the lock however which is quite interesting. The white and pink gold lock has six dials with different letters on it which can be turned to form the correct code: A-L-O-U-I-S.
