Scratched lense

So I have already scratched the lenses on my laser pointer.
I was just wondering does anyone know where to get a new one.
My lenses actually screws out ok and can easily be replaced, I just dont know where to buy em.

Any sources would be helpful, here is the laser that I have.

Tip: Talk to the manufacture...

Thanks, still no joy, I did send em an email last week and no reply yet.
It cant be that hard to find a tiny screw in lens.





I just think its a pain that the lens can be broken so easily.
