13” length with 2 7/8” diameter, 2 1/8” height (plus the top dome) cylindrical prayer case. The top with six silver characters in Sanskrit, the mantra, Om Mani Padme Hum, which translates roughly to purity through enlightenment, repeated on the drum. The top and drum with glass flat back cabochons. Faceted weight on-chain. Slightly tapered carved wood grip. Original inked prayer scroll inside. Soil, wear and aging as typical for Tibetan items. Surely from the migration out of Tibet by Lamist Buddhists in the 1950s after the Chinese takeover.
