Xbox Design Lab Shadow Controllers Just A Skin?

I really want to buy a custom controller from the design lab and I love the Shadow theme, but I bought a Shadow themed controller a couple years back (not from the design lab) and it was just a skin over a black controller. The skin chipped and flaked off
within a year and I'm worried if I got a design lab controller it would be the same thing.

Does anyone know if the design lab Shadow controllers are just a skin? I'm not gonna waste money on it if it's just gonna flake off in less than a year.
