Old OM prayer box

Here is an old prayer / mantra box from Thailand. 
Also called Gau box.

The box is very openable and filled with mantras. You can keep them or change the inside to something you like yourself.

The box measure 4.2 x 4 cm. The metal is probably brass and copper. 

The box is on a leather band to be able to hang it or wear it around your neck, but the leather band is quite old and would probably need to be changed soon if you like to wear it a lot.

The leather band measures 72 cm.
