There is a large variety of Tefillin on the market and a large variety of enhancements. For more information on the topic, you may read the following article.

In order not to burden my customers with research, I recommend a number of enhancements. Different levels may be purchased. The recommended level is “separated until the seam”. The boxes are manufactured in a well known factory, which is located in jerusalem. The factory is known for its high quality boxes and finishing. The parashot are strictly Kosher without any compromises. A handwriting sample may be seen in the gallery.

The price for a pair that are “separated until the seam” is 580 USD.
Talit and Tefillin bags may be added for free. Just mention when you make contact.
