Sleeves For Large Stamp Sheets

Hello, right now I have Lightouse Vario sheets and binders to hold my individual stamps and most of my other stamps. However many of my stamp sheets are too big for Vario sleeves. I like the clearness of the vario sheets. Is there anything out there that you use to hold the big stamp sheets. These are about 9x 10.25 inches in size so I need something a little bigger than that. I'm sure most of the stamp sheet collectors know what I need. Thanks for the help.

I use these for all things philatelic, including panes of stamps. Works great. Provides safe storage at reasonable prices (especially if you shop on-line coupons) as they are readily available at most Hobby Lobby, AC Moore or Michael's craft stores ... and in any variety of sizes to suit your specific needs from business card size to poster size:

Also at Hobby Lobby is a product you can try called Duralar ... It is a thin Mylar wrap that comes in a roll. You can maybe fold and cut to size a little bigger than the sheet. Put a few holes in for the binder. And you have something cheaper than pre made.
