These are nice. They are engraved and infilled with color.
I went with their thinnest aluminum, it would be nice thinner. It did bend easily.
I can send the file to anyone that wants to order one. You could edit it if desired. Choose different colors of anodizing and infill colors etc.
It was $40, including tax and shipping.
Hopefully it will hold up to heat. I have no idea what the colors are made of.
