I came across a couple of unopened boxes of Bear arrows from the Grayling Mi. plant. The boxes are wrapped with clear plastic so you can see the contents. They are Cedar arrows but have plastic vanes? Anyone have a clue how long the put plastic on wood?

Can't say if I have ever seen wood arrows from Grayling with plastic fletch.

All the Bear arrows I've come across the plastic vanes were brittle.

Brittle yes, they fall apart looking at them
