Perfectly safe and looks great
I got this skin in gloss about a year or two ago and I recently took it off because I wanted to switch my skin and I can confirm with absolute certainty that these skins don't damage your switch even slightly! I will say don't buy these expecting the button stickers to work properly though. They stick on fine but Functionally they're incredibly awkward to use for any level usage. I tossed em after the first week of using them because it was just too uncomfortable, especially with the stickers on the circle pads. Outside of that though it looks amazing on the switch as well as the dock. I personally regret not getting matte as glossy looks a bit too toyish for my personal tastes but still overall an amazing skin, and I will be sure to buy from here again.
