Introducing the New
TYNI Product Manual!

In cooperation with AKO (Association of Kashrus Organizations) we are happy to offer our latest endeavor, that made its debut December 5, 2023.
It is a printable yoshon product lookup, that is also a  searchable pdf. It contains most of the currently updated products on Yoshon.com. The Manual gets updated shortly after the website gets updated.

There are navigational links throughout the document. We hope you find this to be a useful tool.
