This pair of tefilin is made from one single piece of leather. It is considered the most durable of all tefilin. Handmade by our sofers (scribe) in Israel and each box is painted in gold with the Hebrew words for "head" or "arm" indicating where to place them.
Please advise in the comments on check out if you would like Ashkenazi or Sefardi. Also if you need for left handed people (worn on the right).
