I re-use the boxes. Mine are an opaque white plastic, some sort of polythene ?, with a clear plastic over sleeve. The sleeve lets me fit in a cover that indicates in someway what I've stored within. I made a very sound sewing kit in one that I take along to a craft class.
They're pretty easy to store sort of storage boxes for small tool sets. Neatly shelve like books
I have a set of pliers for beading in another.
The boxes turned out to be quite useful and robust. No idea what to do with the inners though.
Actually, I do...the tape could be used to wrap around canes to keep pigeons off the seeds in a garden plot
