Finally, I found the perfect file folder for all my 12 x 12 paper and cardstock. Each file folder measures 13.25Hx14.75W so I never have to worry about crumpled corners or crinkled edges. I will definitely be ordering more of these to organize all of my patterned papers, stickers, etc.
I purchased these to go in the rolling cart (Heavy Duty File Shuttle) and they are perfect! The size is larger than 12 x 12, so my 12 x 12 papers fit in them perfectly! As soon as I assembled my cart and added these folders I purchased three more sets! It's great for having papers right at hand!
I looked everywhere for file folders that are well made, sturdy, and will hold lots of 12 x 12 paper. I finally found them! These file folders are everything I want and more. They are a little spendy, however, also worth the price.
