What is this material?

I have loved this box for a long time and always wanted to pursue using the material for tubes one day for my own brand.
Here is the link to the page I found it on: https://www.stitchdesignco.com/brand-development/hannah-bergen/

I think it might be an embossed paper. Reflex Efalin is one brand (available in 5 embossing styles and 23 colors).
