I can send you a holder. The ones I use make it easy to pull a single strip out, and they don’t fall out. They each hold 10 strips - enough for most runs.
For a normal run, the humidity should not be a problem. You don’t use the holder to store the strips, just for use during the run.
The only time I have had problems was with sprinklers, spilling water or gatorade on them, or rain. For just normal runs, even with high humidity, there is no problem.
This way you don’t have to fumble with a container with strips falling out.
