Mezuzah Scrolls, Klaf (in Hebrew)
The most important element of the Mezuzah is the scroll, or Klaf, which is rolled up and enclosed. There are levels of quality in writing, as each parchment is painstakingly written in hand calligraphy as prescribed by Halacha, or Jewish Law. Some scribes have a distinctive beautiful writing and take great care while writing each Mezuzah scroll. The difference between Ashkenaz and Sefardic scroll is one of custom, they are two distinctive styles of writing and have a different order of the paragraphs.
