Sterilite Convenient Home 2-Tiered Layer Stack Carry Storage Box, Clear

just what I was looking for to store canning items love how you can add more to the first two seem sturdy, so that they will withstand all the use they will get

I bought these the other day to store some important craft item I did not want to get broken. I found them very sturdy and easy to open and lock. ..then just by accident I discovered when buying an other set later on the same day that you can attach the second set on to the first 2 level set you bought ...making a stacking tower of 4 levels. ..you just keep adding sets to the desired height you want. Mind you..you will still have to use common sense when stacking and locking these together, the total weight of the items together. Being taller now it will weigh more putting a bit more strain on the locks and handle trying to lift the whole works by the top handle/ After all they are still only plastic...not metal. I still find then very strong and sturdy..well worth their cost they are not expensive at all. For me? I find them awesome.
