You should understand… Proofgrade™ materials are manufactured by Glowforge. If you see it from some other company you should not purchase it. (At least at the time of this writing there are no other outlets for it.) Also avoid any knockoffs that you might see (“Proof-Grade” or “Poofgrade” or the like).
Unfortunately we don’t offer Proofgrade two-tone acrylics at this time. Inventables does sell a two-tone acrylic that they advise is laser compatible, though.

Thank you Dan! I am ordering that now. Where can I find my $50 coupon?
Thanks
It should be in the email titled “Your Proofgrade materials are on their way!” Look near the bottom and you should see an Inventables gift card code worth $50.
And works very well in the Glowforge I will add.
