Handmade by the Hill Tribe of Thailand, this mini button is stamped with the Sandskrit word or sound for chanting: “OM”. Its very sound is sacred and used in meditation by followers of many religions, including Hinduism and Buddhism.With a very generous shank that fits up to 2mm leather quite easily and a solid silver back, it will hold its place nicely in your design. Each one is handmade, so expect variations in imprinting and antiquing. Some shipments the buttons arrive hollow-backed and some are solid... we have very little control over this. Thanks for your understanding.
