Anti-rust Storage For Tools
Humidity can rust your tools relatively easily if your "cave" is located in a basement or garage.
With this storage recipient, with enough space for up to three tools, you will keep them safe. Add some protective oil such as WD-40 to the sponge, and insert your tools in it. They will remain in perfect condition for a very long time.
Several units can be combined as a rack of sorts.
We have to prepare each shipment individually as they are ordered, so allow it 3-4 weeks to arrive in the USA/Canada (to be safe) and 3-6 weeks rest of the world, though they are usually delivered much faster.
