Ikea NYTTJA frames: how to

Recently, i bought few 5X7 picture frames from Ikea. I have some picture post cards, we purchased during our trips. I was lloking for a way to display them instead of adding to the clutter. When I started opening the frames, I found the recycle logo on the glass like front cover is printed on it.How can I use it????

Looking here and there and googling, I came to the Ikea fans website. Actually there is a protective film on both sided and it is removable.

See how easy it is now...I guess, they should give that instruction along with the frame. Now I am ready with my picture postcards...
