Ptil Tekhelet provides genuine Tekhelet strings so Jews can once again fulfill the mitzvah of wearing Tekhelet on their Tzitzit.
About 1300 years ago, the secrets of Tekhelet, this wondrous blue color and the identity of the mysterious sea creature – the Chillazon – that produced the dye was lost. Over the past half-century, a convergence of research and discoveries by Rabbis, scientists, archaeologists, and others has led to the conclusive identification of the sea-snail, Murex trunculus, as the authentic source of Tekhelet.

This year Ptil Tekhelet is once again celebrating Shabbat HaTekhelet in which numerous Rabbis and educators from around the world will be giving classes and sermons to highlight the importance of Tekhelet. Shabbat HaTekhelet is meant to bring the mitzvah to the fore in a positive way to let people know that serious figures are taking the issue seriously, and that a Jew who cares about performing mitzvot should do the same.
An impressive cross-section of Rabbis have put their names to that message.
