Size is 12" x 18" and it is 3.5" deep (not including the carry handle). My long ago deceased Father made this in the 1960's out of wood. I have painted it myself in the past 20 years. It has 6 compartments, each is 5.25 x 5 and 3 deep. Wood handle tool tote caddy craft box made in the 60's. It has some weight to it as it is solid wood. I also have some 'silver snake' skin faux leather which I personally used inside each slot I can throw in (if you like that kind of bling). A substantial piece that can carry heavy items.
