Printfile 45-1 storage

I personally prefer the Printfile 45-1 negative sleeve over the 4 negative per page . My question is this - how do other's store their 45-1 negative sleeves ? I've been thinking of making a wooden box to hold them , but is there a better way ?

thanks- tom

Printfile and Conservation by Design both make suitable archival boxes for individually sleeved 4x5's.

Thanks for the info . I'm ordering now
