Wrong color ultra tread. And defective rod tip.
Ordered a euro rod kit the tip eye was broken/bent flat. You sent out gray ultratread in stead of Blue.
It’s disappointing that quality control in none existent. Then they make so hard to get it right.
Sent pics could have sent the replacement but in their minds it’s all got to go back to them.
Just send new rod tip and the blue color I payed for. 🙁

UTC Threads
I have been using UTC threads to tie flies since 2012. It’s my go to. Predominately 70 & 140 denier. Works well.
