may be shipping a piece that will require assembly as some parts are
too long to ship economically


have seen very very thin plastic sheets used for labeling parts where
they adhere only thru static forces or van der waals

but mostly that was for flat pieces


tape is too messy and post it notes fall off


this is not something i have had to do or thought much about


looking for cheap and reliable solutions
that would mean they stay on in shipping and unpacking and can be
easily removed once assembled


i imagine ikea probably has a large team that does nothing but figure
out how to make fool proof assembly instructions but even then there
are assemblers that will do it for you
