Tefillin are the single most meaningful object a bar mitzvah boy will ever own. We take that seriously.

Every pair we sell is kosher, mehudar, and inspected. Our sofrim are senior, certified, and trusted by posekim across Lakewood and beyond. And every pair comes with a free lifetime kashrus check — because tefillin should be checked periodically, and we want to make sure yours always are.

Tefillin come in three main grades. Peshutim Mehudarim are the entry grade — fully kosher, fully mehudar l'chatchila, suitable for a bar mitzvah boy or someone buying their first pair. Dakkos is a step up, using thinner, higher-grade parshiyos and batim. Gassos is the top grade: the parchment is thicker, the batim more durable, the writing finer. A pair of gassos tefillin will last a lifetime with proper care.

When choosing, think about how long you want this pair to last and what your rav or sofer recommends. A bar mitzvah boy often starts with Peshutim Mehudarim or Dakkos, then upgrades to Gassos later. Many families choose Gassos from the start, treating the tefillin as a lifelong investment — which they are.

Every pair on our site comes with a kashrus certificate, the sofer's name, and documentation of the parchment grade. And every pair is hand-inspected by our staff before it ships. We also offer bag, strap, and retzuah options alongside the main pair.

Free shipping over $75. Free lifetime kashrus checks at either of our Lakewood locations. If you have questions about grade, source, or customization, call 732-444-3111 and our team will walk you through it.

What's the difference between Peshutim, Dakkos, and Gassos?

Peshutim Mehudarim are entry-grade kosher tefillin — fully kosher l'chatchila but thinner batim and less durable parshiyos. Dakkos use thinner batim with somewhat higher-grade parchment. Gassos have the thickest, most durable batim — carved from a single piece of leather — and the highest-grade parshiyos. Gassos last a lifetime; Peshutim and Dakkos should be checked and potentially replaced more often.

How often should tefillin be checked?

The Shulchan Aruch recommends checking tefillin twice in seven years. Many people check annually, during Elul. Our policy: we offer a free lifetime kashrus check on any pair of tefillin purchased from Judaica Square.

Who writes the parshiyos?

Our tefillin come from a rotating group of senior sofrim in Eretz Yisrael and the US, all of whom are certified by recognized rabbanim. Every pair ships with the sofer's name, certification, and date of writing.

Can I get tefillin for a left-handed person?

Yes — we stock itter tefillin (for left-handed wearers). The batim are shaped differently so the knot sits correctly. Select 'itter' (left-handed) at checkout or call us to order.

What minhag options do you offer?

We carry Rashi (the universal standard) and Rabbeinu Tam (worn by many after shacharis, especially in Chasidic and Litvish communities who follow the Ari z'l). Most bar mitzvah boys start with Rashi only. Chabad minhag is Rashi + Rabbeinu Tam from age 13.

What comes with the tefillin?

Every pair comes with parshiyos, batim, retzuos (straps), and a certificate of kashrus. Most pairs ship with a basic bag; we also sell upgraded bags, yad covers, and retzuah-binders separately.
