I am always on the hunt for better solutions. While I like the idea of single item storage jars and boxes that fit inside a larger container because only what is needed is removed, I found that the jars/boxes were sometimes difficult for me to remove with less than nimble fingers.
I then moved on to these strip containers. The locking lids on the larger of the two can be difficult to use as it requires two hands to open. This can be a good thing because if it is dropped, the lids will not accidentally pop open, which could happen with the smaller strip container.
Pro Tip: We all work differently and in different spaces. There is no perfect solution for everyone. Do not invest in more than one storage container unless you are absolutely positive a storage solution will work for you.
