Stop in for a cup of coffee

I have two of them small for 5x8 cards. I stripped them out and use them for Dist leads. Be great for stuff like stamps the way it is. Would love to find one in 8.5 x 11 have a bunch of instructions and breocures to keep safe. Need to find a cheap file cabinet I guess that will fit under my work bench is prob my best bet. Seriously out of room.
Can't tell what size that is for... I really don't have much in sheets etc that would need a flat file for. My best stamps are in albums/binders - either mounted or in pages with pockets made for stamps.
