These are a very special pair of high quality antique prayer books. Le Pouvoir de Marie and Recueil de Prières. They have clearly been used in prayer regularly, the touch of hands is evident, but they have been treated with great reverence. 
Leather bound and embossed twining stems with relief leaves and crosses, there are vestiges of original colouring of the leather. The covers ooze quality, the edges of the pages are gold. 
One dated 1895 and the other 1897, they are in good condition for their age with one loose page I have found in one book, shown in the video and some lose bimding in the other.  Foxing as one would expect with a book of this age.

they measure 12.5x8cm or 5"x3" approximately.
