These are not great pictures but did not want to unpack before having confirmation that they will send a new pair (which is what they are about to). I believe this is the only area bent, around the chainstay fixing end
Suck it and see. You never know. But personally I wouldn't bother for the benefit of having 1 extra mudguard blade, with no fixings or matching blade for the other wheel.
Surprised that's happened tbh. I've folded SKS mudguards in via cack handedness and they normally just..spring back to shape.
Can give it a go, I guess it might end up more brittle but I am not a materials scientist. Depends on what you mean by bent I suppose. Post a pic.
