Jewish Records: How Big Is the World's Smallest Tefillin Set?

One pair of tiny tefillin is located in the "Ganzach Kiddush Hashem" - an institute for Holocaust documentation and research.

These tefillin are so small that their width does not exceed 10 mm. Found tied to a Jew who was murdered by the Nazis, it's surprising to discover that despite what they've been through over the years – they were found to be strictly kosher and could still be used today.

Those who follow the method of the holy Ari often wear two pairs of tefillin simultaneously and therefore would purchase small and meticulously crafted tefillin.
