PSA - Pen loop dust plug for Manta has protective film that should be removed before installation

Hello. I noticed when I was installing the pen loop dust plug in my new Manta it felt a little tight going in the slot. It didn't feel quite right to me, so I removed it for a better look. Turns out one side of the acrylic (?) dust plug still had the protective film on it. If you have ever used sheets of acrylic or plexiglass for a project, you know it ships with a thin film to protect it from scratches. I removed the film and the dust plug went in smooth. I just wanted to let the community know.
