There are Many things that can render Tefillin or Mezuzah not Kosher or at best minimally Kosher.
Some of which happen over time with aging and some unfortunately are Posul from the get go.
Letters, words and or Tagim that are missing, extra substituted, touching, Broken, Improperly Spaced, misshapen faded, cracked and weather damaged.
We document the problems we find and periodically upload them to the website.
We hope that this will educate and encourage the public to purchase only Tefillin and Mezuzas that are high quality from a reputable source, to take care of them properly and have them checked regularly.
One of the many benefits of purchasing your Tefillin at the Sofer Center. Come experience the joy! Watch as Rabbi Kass puts the Parshios inside the Batim. learn all there is to know about your Tefillin. Connect.
The owner of these Tefillin was 27 years old getting his Tefillin checked for the first time since his Bar Mitzvah.... it was heart wrenching to have to let him know about this.
Out of the thousands of Tefillin we have checked we have found this only a handful of times... For this reason alone, it is important to have your Tefillin checked regularly... How many more years could he have gone on wearing problematic Tefilin?!
As you can see here it is says Lo instead of Lecho. This Pesul can not be fixed. for more information follow link what you should know about Safrus
These Tefillin were left outside overnight and got rained on. The letters bled into each other. and cause these Tefillin to become not Kosher.
Whatever the situation be sure you keep your Tefillin with you at all times and never leave them outdoors.
These Retzuos started out as 15mm (as you can see the one on the left) and were stretched to the point where they are now less then 9mm (Retzuah on the right),
The preferable width is 11mm according to the Chazon Ish and 10mm according to Rav Chaim Naeh. The minimal width for making a Brachah is 9mm. If a Retzuah has been squeezed together at one spot making it less than the minimal width but it can be pulled back in to the minimal width it is acceptable . If however it has been stretched out and is narrower than the minimal width at any spot it must be replaced.
The end of the Retzuos may be cut on an angle even though they will be less than the minimal width.
Lesson: Do not tie the straps on very tight or wrap them on the box very tightly as this will lead to eventual stretching and invalidating the Tefillin straps
Two letters touching in Tefillin make them not Kosher. The reason for this is that the Torah says Ukesavtom and we learn out that the letters have to be Kesivah Tama.
One of the ideas of Kesavah Tama is that the letters need to be separate from each other and be totally surrounded by Klaf.
Being that these letters which are touching do not loose their own letter status or together form a third letter this is an easy fix, it is only necessary to scrape the connection and it will then be Kosher.
Every letter needs to be surrounded by Klaf. Should the hole be along the letter it would make it not Kosher.
As you can see here the Mem has a hole inside. but the hole is not touching the letter itself therefore it is still kosher.
