I had 5 balsa prop lures come in yesterday's mail and just opened them up and am currently examining. 4 of brand 1 are what I expected but my single example of brand 2 which is $5 higher than brand 1 and sells for $26 shipped seems questionable. The wire that runs through the lure can be slid back n forth perhaps 3/8" and shows the unpainted unsealed hole on each side. What should I do to this lure to keep water from filling the hole and maybe saturating and potentially ruining the unsealed balsa? Does the wire need twisted more to tighten this up?  Maybe I'm overthinking this? 

Send em back ?
