Manual steel counter, perfect for counting prostrations,
for long Mantra practice sessions
or to discreetly count mantras in public transport,
while driving or walking.

There are many hand counters on the internet,
which are often less expensive than those I offer,
but whose "shell" is in silver plastic (mine are in steel)
and whose soft plastic mechanism will let you go pretty quickly
and at the least opportune time.
