I've not shot any of it yet lol, but I guess I should give it a go and see how it holds up. It's pretty thick compared to a goggle lense. I know that's meant to take the impacts, but slightly thicker stuff should be okay with the odd hit.
I'd be cool with doing them for you, just pay a couple of quid for for postage and if you're happy, you could pay me what you think they're worth ?
I'm not a rapid production company by the way, I don't have loads of spare time, but I imagine they'd be done in a couple of days. Possibly ready to post out by the weekend ?
If you get some Perspex, there's nothing stopping you from marking some up and cutting your own. You can colour them, leave them clear or put a custom image between the frame and Perspex...
