Fire staves are notoriously difficult to travel with and usually leave black, sooty marks and a trace of paraffin everywhere they go. A staff case doesn’t only keep the smell and dirt contained, but it also protects the grip and wick on your staff from unnecessary wear and tear.
It is not recommended to store a freshly used staff in its case for too long straight after burning. The paraffin fumes may get absorbed by the grip which will make it slippery and stretchy. If this does happen, leaving your staff out of its case for some time will dry out the grip. To avoid this, leave the staff out overnight after using it in order for the paraffin to evaporate.
