Whatever the situation be sure you keep your Tefillin with you at all times and never leave them outdoors.
There are many things that can render Mezuzah or Tefillin not Kosher, or at best minimally Kosher.
Some of which happen over time and some unfortunately are Possul from the get go,
Letters, Words or/and Tagim that are Missing, Extra, Substituted, Touching, Broken. Improperly Spaced, Deformed. Faded, Cracked and weather damaged.
We document the problems that we find and periodically upload them to the website.
We hope that this will educate and encourage the public to purchase Tefillin and Mezuzos only from a reputable source, and to have their Mezuzos and Tefillin checked regularly.
