product works very good does exactly Wht it supposed to simple a quality product that helps me do my job a lot easier as a professional haircut stylist

I received the pen without its packaging and ingredient list. The packaging didn’t even have any MSDS safety labels. I received an MSDS doc from supplier but the packaging didn’t show that the content is highly flammable. I want the supplier to provide evidence that the pen is natural, plant based formula and is non toxic and safe to use. Also, the supplier should provide evidence the pen is non flammable. Thank you.
