Continuing with the topic of ink, which seems to be our topic of interest at present, I have a question for Yehoshuah to please ask Rav Shammai Gross Sh';
If a company representative tells a customer that no animal by -products are in a specific ink can that be relied upon from a kashrus point of view?
The reason why I ask is because I understand that the common use in the ST'M industry of Staedtler "Paper 745" rapidograph ink for uses such as tiyyug, tikkunim etc, was based only on telephoning the company and asking if any animal by-products are used. Lab tests were not conducted independently by the rabbis allowing the use of this ink.
I was also told by reps here in Australia that no animal by-products are used.
Can I rely on this?
While I currently only use dyo lanetzach rapidograph ink which has a hechsher, I'm more worried about the past, I have used the ink for tikkunim based on rabbinic advice that it was OK, and even now I do sell some cheaper mezuzos, tefillin and even sifrei torah that have had rapidograph tagin etc made with Staedtler "Paper 745" rapidograph ink. I cant imagine anyone who sells Sta"m that has not sold a cheaper item esp a sefer Torah with tagin made by a metayeg with such ink.
