Rubber

Rubber is a material that can be gathered regularly from Jungle Log by building a Sap Camp. It functions as a substitute for Tool in shoemaking and for Beeswax in the production of Copper wire.

When Rubber can be imported or otherwise obtained in bulk, it is usually more efficient to use it for these recipes instead of the original materials. This makes it a useful alternative resource for maintaining production chains that depend on shoes or wiring-related crafting.
