Protector for Tefillin shel Yad

description of book New and exclusive patent! A cover for tefillin shel yad was manufactured to protect the tefillin when in use from friction against the garment, body, and any other abrasive factors. The erosion of tefillin corners, damage to the square corners of the housing, and peeling of paint are damages that might be caused without protection. The Gedolim of Israel recommend the use of a covering for the tefillin shel yad from the words of Rabbi Asher Weiss Shlita, “and there is a hidur mitzvah and a proper ruling for it.”
