They're in Bnai Brak. The fact they're selling tefillin on Amazon, etc. starting at $157, leads me to be suspicious. I am on a campaign and I told someone that his tefillin were pasul. He ignored what I had to offer and went online to shop for tefillin even though I warned him that Amazon, eBay and Judaica shops are not the place to purchase Stam. When I saw he didn't care and was more interested in the price I offered to contact the seller and request specific information about their basic gasos. He ignored that offer as well. Amaratzus.
