Hi,
I had ordered a Book Armor case for my new Sony 505 reader for a upcoming trip. A few days ago I was notified there would be a delay in shipping it

so might not have it before my trip. I checked out several stores and could not find any that had a case for this reader. Several people commented that they had used day planners. I found a perfect planner that is a perfect fit by Blue Sky. It also zips all the way around
I added elastic to hold the planner in- could have used Velcro but did not have any. Then removed the panel on the left side (that has card slots) since didn't want anything that was not flat touching the reader. I also glued a few pieces of the cardboard that came with the reader and a couple pieces of foam sheets (that can be found at any craft store) to the left side to enhance the protection. This "extra" protection might not have been need but wanted as much as possible
The Blue Sky Planner was $ 14.39 from Target. It measures approx: 8x5 1/2 inches. Another nice thing- the planner calendar, address book is in one small spiral notebook that can be easily slipped out and placed in your bag or purse.
I hope you can see the pictures I have attached- FYI the planner is black not green as it appears in the photos.
