Open bins
Useful for fast access when dust protection is not important.
Closed boxes
Better for low-use storage when contents are labelled.
Clear containers
Helpful when visual identification matters, but transparency does not replace categories.
Handles and weight
Large containers become awkward when filled with dense items.
Practical boundary. Measure first, respect product load limits, and do not improvise wall, ceiling or overhead installations when the structure or appropriate hardware is uncertain.
