J5 has been using these for years to keep parts and hardware organized. They are clear so you can easily identify what's inside, and the screw top lid means that whatever is inside stays there without worry of the lid accidentally popping loose like some other containers out there.
This size is 1 1/2in (38mm) diameter and 13/16in (21mm) tall. They fit great in the top of the Plano 5231 that is so popular for tool and parts storage- without dividers you can fit 8 of these Small Parts Organizers per row. (See below)
