I have read several string on Bangle sizer and did not realize there
will be such a big demand. I would have posted that this is
available at 46 jewelry Supply for $9.50. You can order it through
them on the net. It is very convenient as there is one Bangle, which
can be enlarged and tried for fit. The size is stamped on the bangle
itself and this tell you the length of material needed.
