I built a rod tube today in anticipation for my TFO Proffessional 8' 6" 3wt, That will be coming in the mail in a few days. It only comes in a rod sock so I figured I should build a tube for it for protection. I also Wrote the rod details in metallic sharpie, Then put a bit of clear coat spray paint over the whole thing to give it some gloss and keep the writing from getting scratched up to badly.
Heres a few pics:

Total Cost: $5.00
Can't wait for the rod to get here.
