The bottom part of a Elite Trainer Box is covered in some sort of fake leather. Is it just plastic?

Hi there, I was bored so decided to watch the new Pokémon horizons series featuring new protagonist Liko. I was surprised how good this was, the concept of adventuring without gyms, not too many Pokémon but getting good with few, the characters, the storyline, no annoying team rocket, an even cooler Pikachu (sorry to hurt OG Pikachu fans). Definitely will recommend a watch, I am currently at 40th episode, and it just keeps getting better, the characters are amazing, and the bad guys are really cool too, slightly more competitive than team rocket (expecting them to put even greater fight).
