I was looking at a Star shaving brush online and was wondering if anyone is familiar with them. Tried to attach a pic but it wouldn't take the file. It is said to be a 1980's era, has a white knot (boar or synthetic?) and says "Set in Rubber" and "Sterilized" USA beneath the Star brand. Looks like and Eveready. I didn't know that they branded them as Star. Anyhow I'd appeciate any information about what the knot might be and anything else you might know about this sort of brush. Thanks.
