no no , dun buy those. There's another type of files at popular, especially made for neg/slides. Cost $18 with some sheets inside.edlye said:Popular has 3 Ring Binders that they call "3D Files", these will take sleeves with 3 holes. The binders are not the oversized types though, so you will have abt 1-2cm of sleeves sticking out at the sides width-wise.
