Our tzitzit are made out of 100% cotton cord, and are sold as a set of four. We do not offer the special snail dye called "Techelet". Each tzitzit is individually hand tied to insure the highest quality. We often have customers ask questions about why the tzitzit are tied the way they are. Below is a brief explanation.
The first tying (pictured on left) is called "Traditional". This is the tzitzit that most Jews use.
By its construction and the name, the tzitzit reminds us of the 613 commandments. In Hebrew, tzitzit is spelled Tav-Yod-Tsaddee-Yod-Tsaddee. Each Tsaddee has a numeric value of 90. Each Yod has a value of 10. The Tav has a numeric value of 400. All together the word "tzitzit" has a numeric value of 600. (Tsaddee 90, Yod 10, Tav 400. Thus you have 400+10+90+10+90= 600.) Each of the tzitzit is made up of 8 threads, and tied with 5 knots. 600+8+5=613, this reminds us of the 613 commandments.
The second tying (pictured on right) is called "Adonai Echad".
Adonai Echad is Hebrew and in English means "The LORD Is One". Each of the tzitzit is made up of 8 threads, 5 separate windings (Tzitzit is 600+8 strings+5 windings=613) so not only do your tzitzit spell "The LORD Is One" but it also reminds you of the 613 commandments like the Traditional do.
We hope this gives some answers to the questions regarding tzitzit.
