I can make a pocket protector for free. 3 dollars pluss chipping and handling let me know if you are interested. I was looking for mine over the internet and did not find it the way I like it so I made it myself. Here is how I made it incase you want to made it.
Get a gallon of milk better transparent. cut 2 U shape like the size of your pocket. with like a inche on the side to kind of wrap around the other u side shape, then staple it the U shape part and leave the opening without staple of course. Then you put tape around or actually you cut put the tape around 1st then the staple. This avoid any link from coming out. or you could do tape (the transparent one) before the staple and then after the staple, just a little bit. And there is our self made pocket protector. Mine I had it for a long time. easy and helps to recycle.

If you want to see picture let me know where to email it to you so you could have an idea.
