Buying used snap-on box Vrs new bigger china box

I was a MAc dealer from 84 to 93 and a Snap On Tech Rep from 93 to 99......My 1988 (50 year anniversary) Mac boxes are in the garage right now and over loaded like crazy and they still look good and drawers slide fine..........and these are before the ball bearing slides came along. You can see them behind my Suzuki.............
