A simple wooden pallet like you know it from industrial sites and warehouses. They are usually very worn and used, but rugged and super reliable nonetheless. Sometimes they can carry weight loads up to a 1000 kg!
This model comes with 2k textures and yields great performance along with decent quality. It's just one of those props you'd put in your game's levels when you don't really know what decorations to add in anymore, just like barrels. Barrels are awesome!
