flash binders

Hi All, was hoping someone could refer me to where I could get some good quality 11x14 Flash/design binders. I used to get them from National but am told they now only have the zippered style and I do not want/like those. I don't usually buy much flash, 95% of my work is custom but occasionally I buy some flash to jump start some peoples imagination and I recently bought some and need the binders to let clients look at them....Doc

We get the same ones that National use to sell without zippers at hobby lobby....dick blick art supply also carries them...T
