Bakelite caps are not the best to use
from my experience here at Bishop.  The smooth surface of Bakelite
makes it very difficult to grasp-twist and its breakability are real
negatives.  Each time we replenish alcohol in our collection, most bakelite
caps are wasted because we have to break them in the process (gently
tapping with handle of screw driver or whatnot).  Now, we are replacing our
bakelite caps with black soft plastic caps with vertical ridges on the cap
rim so they are easy to grab and twist and they don't break. My
other suggestions:  keep your alcoholic collection in very cool environment
to slow down evaporation, which then you can close jars tight but not too
tight that they would be impossible to open.

Hope this helps.  Aloha.
