It is part of nature and behaves as such. Each jar is unique, and it has a distinct wood grain pattern. If the jar is exposed to extreme temperatures of fluctuating moisture, it may react.
Wood has a natural ability to absorb some moisture, and it needs time to acclimate to new surroundings. When in a new environment, it can take a bit of time before it can fine-tune its moisture levels, and the lid might feel loose or tight to begin with.
Store in a dry place, but don´t worry if you accidentally forget it somewhere damp. Once you bring it back to a dry environment, you can recycle the jar. You can burn it, compost it, or take it to a wood recycling centre. The jar is made entirely of wood and it won´t burden the environment.
