I had bought some time ago 3 Spell Master Stanley 1-94-745 reference and I found them very practical to put my screws, nuts and other small parts. Having boxes still need to continue to store small parts I recommended 3 boxes of the same reference. They have clearly evolved into better but I can not stack the old well on the new and vice versa, which is a shame. The former had a central closure on the cover to prevent it from opening accidentally, on the new system is replaced by two side closures which also help keep the boxes they come. This system is convenient because it keeps the boxes they come in case of transport but less so in the case or like me you just stacks the boxes to store them on a shelf. Finally the evolution is nice and if the lateral system maintains is not used simply to block the low position and it does not interfere.
