Has anyone tried “Carved color paper” like this? https://www.aliexpress.us/item/3256802561471048.html
I assume it works similar to Cermark, but in a different form. I only see it listed on a couple of sites (AliExpress and another non-US site), so not sure if it doesn’t work as promised or is just so new that it hasn’t reached the US retailers. (if it worked, I’d think there would be someone on Amazon US reselling it).
If it actually works, it looks like a great way to apply color to glass.
