The Morinaga BF-1 Infant Formula is a complete milk powder designed for infants from birth up to 12 months (though some retailers specify 0-6 months for a particular packaging size).

While I can provide general details on the BF-1 formula, a specific 600g box size for BF-1 appears to be less common than other sizes like 400g, 700g, or 900g based on available retail information. However, other Morinaga formulas, such as the BF-2 Follow-up formula, are commonly sold in a 600g box.
