Tefillin straps are made of leather which are made of special straps for the purpose of performing tefillin. Of all the parts of the tefillin, the straps are the most vulnerable part since it is all wrapped around the person’s arm. New straps give a feeling of renewal throughout the tefillin.
Tying the straps every day exposes him to 2 main problems: absorption of sweat and oils on the body of the laying person, and strong stretching of the strap. Usually replacement straps every few years.
The tefillin strips and their integrity are extremely important for maintaining the kosherness of the tefillin. If the straps are disqualified, all tefillin is disqualified. It is important to check them once and make sure they are not damaged.
