Review on Premium 8 Inch Nylon Tube Brush Set - 12 Piece Assorted Variety Pack by Tonya Brown

That's exactly what they say: an assortment of brushes for use on glass tubes of 2mm (just over 1/16"" ) to 38mm (about 1 -3/8"). They're pretty hard and abrasive so I wouldn't use them on clear plastic tubing, but they work really well on glass. I only needed three, but the Price was so good for the whole range that I bought them all and kept the rest in reserve so as not to crease them in the print part when I use them and I twist them towards the wrap (as if tightening) if I twist them on principle to avoid untangling the wire However I would buy them again That's a good price for three of these brushes, a good deal for a dozen As always YMMV.
