Brand is Geddes. Doesn't say what they're made of. Just says "finest quality bristles" :/ Their total lengths range from 6 1/2 inches(handle & brush) to 7 1/2 inches & brush widths range from 1/8 on smallest to 3/8 on largest. Does that help? I don't know much about them. I got them in some things from a house I was cleaning out. Thanks for your interest:)
