Don't get the reasoning behind that but its all good... No knot should have glue coming up the sides...period... It reeks of poor production!!If it were natural hair, I'd worry... with a synth knot... meh.
I watched the video above again and was curious as to which Simpson brush it was that they were gluing the knots into and then it dawned me that that knot has a plastic ring around the base, (like the ones that Omega uses), of the knot which peaked my curiosity even more and have been searching for a Simpson brush with a knot in it like in the video and have only come to the conclusion that I don't believe those are even Simpson knots at all!! Is this a video from Omega and not Simpson? Can someone verify this?
