A new independent investigation into tefillin sold by Judaica and STaM retailers in Brooklyn has uncovered troubling findings that raise serious questions about quality-control practices within portions of the industry.

The private investigation, conducted by Rabbi Moshe Yisroel Dovid Wolf, involved the purchase of the least expensive pairs of tefillin sold by nine different Brooklyn-area retailers. The tefillin were purchased anonymously, documented on video, and submitted for a blind examination by an experienced sofer who was not told which store supplied any particular pair.

According to the investigation, more than 60% of the tefillin examined were determined to be either pasul (halachically invalid) or b’dieved (a level that may fulfill the mitzvah after the fact, are not allowed to be worn again after the findings are revealed,  and definitely should not be sold to consumers in their present condition).

The findings were subsequently reviewed by the renowned Posek Rabbi Avraham Tzvi Wosner of Monsey, New York, who issued the final halachic ruling on each pair. Rabbi Wosner heads the rabbinic oversight of Vaad Mishmeres STaM (VMS), widely regarded as the world’s leading organization dedicated to ensuring the halachic integrity of Sifrei Torah, Tefillin, and Mezuzos.

After reviewing the findings, Rabbi Wosner expressed deep pain over what had been discovered. Rabbi Wosner remarked in Yiddish: “עס טוט אזוי וויי אז זיי פארקויפן די תפילין” (“It hurts so much that they are selling these tefillin.”)

Rabbi Wolf stated that Rabbi Wosner’s reaction reflected concern not only for the specific deficiencies found in individual pairs but also for the broader responsibility of those who sell STaM products to ensure that every pair of tefillin reaching a customer has been properly checked and verified.

“This investigation was never about attacking any particular store,” said Rabbi Wolf. “It is about protecting consumers and raising awareness. Most people assume that if tefillin are being sold in a reputable Judaica store, they have already been thoroughly checked and verified. Unfortunately, the evidence suggests that assumption is not always justified.”

“Tefillin are handwritten by human beings, and mistakes can occur at every price point,” Rabbi Wolf explained. “The issue is not whether mistakes can happen. The issue is whether those mistakes are being identified and corrected before the product is sold to the public.”

The investigation also revisits a longstanding ruling regarding STaM in 1987 issued by the Crown Heights Beis Din, which stated that local sellers of STaM must verify the kashrus of the products they sell and may not rely solely on quick wholesale inspections performed in Israel prior to being sold.

The complete investigation documents the purchase of the tefillin, the opening of the batim, the examination of the parshiyos, the findings of the sofer, and the final rulings issued by Rabbi Wosner.

Rabbi Wolf hopes the project will increase consumer awareness and encourage higher standards throughout the STaM industry.

“The goal is simple,” Rabbi Wolf said. “We should all be able to take for granted that the Tefillin that are being sold in religious stores are Kosher. Our sages tell us that the Mitzvah of Tefillin brings blessings to the individual who puts them on, adds protection to the entire Jewish community, and hastens the Geulah. When a Jew spends hard-earned money to buy tefillin, he deserves confidence that what he is receiving has been properly checked, meets the standards that were promised, and that he will fulfill the Mitzvah while putting them on.”
