Description
Radzin Techelet is worn by many Breslov chassidim and others. Hand-spun tzitzit with dye made from cuttlefish.
Note that unlike Ptil Tekhelet, Radzin Techelet is normally sold as a package of four blue strings only, so we list an option to add a set of white strings as well. When choosing the white strings, if you would like information on the difference between machine-spun and hand-spun, please refer to this article.
Rambam or Raavad?
One of the options you need to select above is “Rambam” or “Raavad.” This refers to the way the blue strings are dyed. Four strings are inserted into each corner, so that you see eight strings hanging down on each side of each corner.
According to the Rambam, on each corner you should see one blue string and seven white strings hanging down. Therefore the “Rambam” set is dyed half blue, and half is left white. This approach is followed by most Sephardim and Chassidim.
According to the Raavad, on each corner you should see two blue strings and six white strings hanging down. Therefore in the “Raavad” set the four strings are dyed all blue. This approach is followed by most non-Chassidic Ashkenazim.
Tying Customs:
If you have never tied techelet tzitzit, you may want to tie them according to the Raavad, Sefer HaChinuch or the Vilna Gaon.
If you know how to tie Chabad tzitzit, you can tie according to the Arizal. The Rambam custom can be quite difficult at first, and is not recommended for the uninitiated.

After doing research and a lot of reading over the past two years, I finally concluded that the Radzin method of techeiles is the real deal (meaning that the cuttlefish is indeed the chilazon). Ben himself mentions that Radzin techeiles strings tend to bleed, wear off on your fingers, etc. but based on my experience this was not the case.
The thick strings are beautiful, and the blue color is rich and deep, which looks so good combined with the white strings.
Tied the tzitzis according to a Breslov method.
If you would like to view a video talking about why the cuttlefish is the chilazon and the Murex Trunculus snail is not please see this: https://www.youtube.com/watch?v=zKhbhTkrGtQ&spfreload=10 It is a great resource for those still deciding whether to get Radzin or Ptil Tekhelet.

This is the real techeles according to all requirements and description. The techelet dye is revealed yet!
Richard Jones –
Just what I was looking for. I hope you’re better at tying them than I am though. I ended up with blue fingers, but I’m happier with blue strings in my Tzitzit.

A bargain and just what I needed.

I have no doubt this is the right blue after much research.

These have been great. Great quality, we’ll buy again.

I really like these. My only complaint is that the dye comes off on your fingers. A quick rinse with water and some time to dry will solve that issue though. They look great.
Rabbi Yehoshua Ben-Avraham –
Great service and looking forward to letting others know that working with Ben’s is worth the effort!

I have been wearing Radzin techelet for several years now. These are the real deal! Based on everything I have read on techelet and the chilazon (with all its descriptions and requirements in Jewish sources), this is the Biblical techelet. High quality. I prefer the thick techelet as opposed to the thin strings. Ben’s Tallit Shop is my source for genuine techelet made by the Radziner Chassidim in Israel. Highly recommend this product!

I had Ben’s tallit shop send me tzitzit strings and a katan and they did an awesome job getting it to me quickly and when I had questions they were super helpful. Thank you so much!

Genuine Techelet from the Biblical Chilazon! -Re-discovered in 1887 by the great Talmudic scholar Rabbi Gershon Henoch Leiner, from the squid which possesses all 11 signs that our Sages gave us to identify the marine source for Techelet- Biblical Blue, comes Techelet, which the Rebbe’s Chasdim have worn since his re-discovery. Techelet made by the Radzin Chasdim, excellent quality which enables every Jew to now fulfill the mitzvah of wearing Techelet, which completes the mitzvah of tzithzith. I highly recommend this product.
William Cook –

David W –
The Tzitzit came in very quickly and are exactly as described. I was impressed with the online resources to learn how to tie the strings. Excellent service.
