Storage Binder

Storage Binder
Can anyone tell me if it is a three-ring folder that is installed there in the animation Acme standard drill?

I am a very lively and I have to carry around hundreds of frames in a time of shoot-pencil tests. Acme I work with three-hole standard punch record, but I can not find a folder set to ring the opening set. It is extremely inconvenient to carry around these sheets, and difficult to keep them organized. If anyone knows where I can find something, please tell me. If not, then I'll settle for any practical means of storage. Thank You.

Hello, sorry but I have no idea how to help in this matter. This is the only way I could know in touch with you because I do not use AIM and do not allow email. Although I thought it might be the person who could help me a lot .. Thank you.
