I've seen a few ways. Some sample kits come with
them in small glass/plastic vials with tight fitting
plastic lids (kind of like the iron fillings bottle
in my old chemistry set).
The other is use the cabinets with small drawers but
have the parts on tape. They are shipped on tape-and-reel
so you take strip of the tape (a foot or so) and place it
in the bin. This I've used more often.
Many SMT parts do have codes written on them
(you may need a magnifying glass). The resistors often
have the value 103 = 10K etc, and the caps use a special
alpha numeric code which you generally need a table to
look up the value.
