Unfortunately, i was sufficiently..ahem...'disappointed' at the 100% 
price increase from the time i ordered to the time the filter arrived, 
that i neglected to ask for a swatch book. The folks at the store did 
not, i think, have one.  Anyhow, i have since ordered the 'lifetime 
supply' of #27 and #95 roscolux gels, so i should be able to experiment 
ad lib...

My filter did not come with any warning other than "keep in a cool dry 
place" and "handle these filters by the edges, once marked or soiled they 
are difficult [!] to clean".

My new 44A came inside a molded clear plastic hinged folder, which is 
probably more robust than the previous packing material, but probably 
harder to keep clean and safe when opened.

The last Wrattens i bought came packed in a light cardboard envelope, with
the filters inside a foil wrapper, protected by a tissue sheet which
covered each side.  I have had these filters for over ten years, and have
used them in the Sierras, the Olympic Penninsula, Yellowstone Park, and
other reasonably rigorous enviornments.  i am careful of them, they are in
cardboard holders, i use them behind my viewcamera lenses, and i unwrap
them only to put them inside the camera.  i have not had any problems from
environmental conditions yet, and only acquired a few light scratches on 
them, which i do not believe hurt image quality.
 
They have certainly been in conditions that were not 'cool and dry', but
not for extended (days to weeks) periods.  I don't think they will melt or
decompose at over 73 degrees, but i expect that heat and high humidity
will mess up their optical qualities--i imagine they are rather
hygroscopic. 

It will be a bit of a wrench to take a scissors to my $30 Wratten filters, 
but a 3dman's gotta do what a 3dman's gotta do.

How much worse are the results using the roscolux gels compared to the 
Wrattens, if i am making direct in-camera Polaroid 4x5 color prints?
