Review on ESR (2-Pack) Paper-Feel Screen Protector for iPad Pro 12.9 2021 & 2020 & 2018 - Write & Draw on Paper-like Surface, Anti-Glare Matte PET Film | Supports Pencil | iPad Pro 12.9-Inch 2021 & 2020 (Not Glass) by Buffy Nystrom

These are definitely not 2 packs. Except 2 films covering the top and bottom of the tread. Second, it's too small to cover the entire screen. It covers the writing surface but doesn't reach the edges of the tablet. That being said, the installation guide, which would be a cool idea if I used it, would have uncovered screen space. Maybe they sent me the wrong size? This does NOT apply to 12.9 and does not apply to 2 packages. Yes, there will be bubbles, but no more than any other protective film installation - you just have to be careful and work them out. Also, they can show more because of the matte finish. I had no problems with blisters.
