The OM pendent was called a Mimi pendent.  I assumed "Mimi" was the maker.  If I had realized it was a typo and should have been 'mini', I wouldn't have bought it.  It is way too small for my purposes.  If you want a small, charm-sized OM, this one is well-made, nicely crafted.  I was very disappointed.  The vender made their sale, but I won't buy from them again.
