Very tightly packaged, so be extra careful in retrieving the protectors from the packaging. The instructions on how to apply the protectors are on another transparent film, that needs pulling off first. This part is not mentioned, so I was a bit confused for a minute of two. I would have like the instructions on a small additional coloured instruction leaflet, and a bit larger perhaps to see properly. I am being pernickety perhaps, but for what they are, they are expensive, and it would be quite easy to mess one up if it is not done carefully. When I put the first top protector, for a minute I thought that it had not stuck, but it went on perfectly, and exactly the right size. After that, the bottom one went on in a blink of an eye. No problems with air bubbles. I would recommend that careful cleaning of the screens are done before application, with a high quality anti-static lens cleaner first, so that no extraneous dust is trapped on the screen before applying the protective cover.
