Oxford Twin-pocket Folders With Fasteners - Letter - 8.50" X 11" - 85 Sheet Capacity - 3 Fastener - 0.50" Folder Fastener Capacity - 2 Pockets - Leatherette Paper - Black - 25 / Box (ESS57706)

As a CPA, I have been using these portfolios in my tax practice for over 30 years. I use the front pocket to place the e-file signature forms, instructions and invoice for the client, and the back pocket for client's original tax documents, with tax return copy secured with three fasteners. This way, all the stuff is ready to get a jump start should there be an audit. Clients who have collected the “Blue Folders” over the three decades report the portfolios hold very well. Leatherette grain finish makes great presentation.

I bought these to use for business presentation and they are very professional in appearance and very durable. They are a little pricey compared to others, but they did the job for me at the time.
