No information about total length. Too small.
There's no information about the total length, even at the thread spool. The thread consist of three twisted (not braided) filaments, each one made of parallel fine strands of polimeric fibers (melts with heat). The thread is waxed but too stiff. I believe 0.45 or .55 mm are more suitable diameters for most cases (small to medium pieces). The colors are much darker than the example pictures. Take that in account. At the photo: top line 4mm round prick iron chisel, middle 4mm diamond shaped chisel and bottom, 3.85 mm French chisel.
