I've been noticing small hairline cracks in the wrapper of a fair number of sticks that I pull from my humi. They are not severe, most about 1/8" to 1/4" in length and they appear to be mainly just through the wrapper and don't affect the binder.....but they do sometimes affect the smoke volume until the burn gets past them. Rh has been steady between 65-69 for several months, temp runs around 70-72f consistently.....no spikes on the min/max readings for either temp or rh.

Do these cracks appear over time normally? Am I possibly not inspecting them closely enough when I purchase them? Don't think its handling damage as I try not to move them around too much when selecting smokes.......I'm a little confused.
