I’m trying to find tags to use at home for labeling. Will these work with a CO2 laser? My guess is yes since it is anodized aluminum.
I would think so, it does say that in the the product description.
Well yes, but they could be talking about fiber lasers, sharks with freaking lasers on their heads, or something other than what I have. Just wondered.
Ohhh laser head sharks are the best. 
I need fixed labels for my RV, paper labels keep peeling off.
Been thinking about acrylic with filled lettering.
I tested the aluminium labels from Cloudray. They work fine in our Trotec Speedy 300 (75W Co2).
They are very flexible and do not tend to buckle or break.
