We recently found a new source for Tibetan malas outside of Kathmandu Nepal. We have purchased a lot of one of a kind malas from him as well as some small supplies of really beautiful traditional bone malas. This one has 108 bone discs and 9 naga shell spacers. It will not fit over your head, but should fit twice around your wrist when not in use. Very limited supply of these beautiful malas.
Size: 11mm by 1mm discs with 9 15mm naga spacers
