A Jerusalem court ruled that a tefillin travel case made by Art Judaica is an imitation of Tefidanit, a tefillin case made by Tefillin Beit El, and ordered Art to halt sales of the product.
The tefillin cases also have space for a tallit, siddur and other items. They are quite popular among the knitted kippah sector in Israel and among IDF soldiers.
When I was in the army, instead of buying one of these tefillin cases, I simply used a very hard and sturdy square tupperware container that was a perfect fit. Be aware that according to halacha once a container is used for tefillin, it cannot be switched back to regular use.
Tefillin case copyright upheld
Jerusalem District Court Judge Ben-Zion Greenberger said the Tefidanit copyright was valid and ordered Art Judaica to stop selling their tefillin case in six months or face an NIS 50,000 for every violation.
