varastosta
Varastosta is the elative case form of the Finnish noun varasto, meaning a warehouse or storage. In Finnish, the elative (-sta/-stä) marks origin or source, often translated as “from” in English. Therefore varastosta expresses that something comes from a storage location: from the warehouse, from storage.
Examples illustrate its use. Toin tavarat varastosta. (I brought the items from the warehouse.) Tuotteet tilattiin
Grammatical notes: varasto has the plural varastot, and the elative plural is varastoista (from the warehouses).
Overall, varastosta is a standard, neutral way to specify that something originates from storage or a warehouse
