Potential prayer wheels that are available.
These start from the least expensive up.
Over the years I have carved and sold many alabaster and marble prayer wheels.
I have a couple that I first learned on sitting around and thought that rather than keep them I could offer them at a reduced rate. Please note that those in the third and fourth rows are not yet mounted on the bearing and once they are that raises them approx. 1 inch above the base.

The following two photos is of a beautiful alabaster prayer wheel. Since it is pretty delicate I offer it for $150.

This alabaster prayer wheel was wounded in action and has a slight chip around the upper rim where the lid meets the rim. I've sealed it there to fortify it (therefore it cannot be opened.) It contains over 150 million Om Mani Padme Hum mantras on microfilm. $150
