Sewin, Squirrel hair tube's.

Here are some tube's,that i use for my sewin fishing.
they are all tied on Aluminium tube's, which i use a lot more than any other type of tube. i find it light enough to cut to size, to suit all my fishing needs.
if i need heavier tube's, i will add cones. or cut tubes to size out of brass or copper, 
I buy my tubes in packs of 5 x 12" inch long lengths,
It is tubing, that is used for modeling,
the ones here are all 11/2" inch long. and i cut them to other sizes, from 1/2" inch to 21/2" inch long.
