Pigeon Products

From what I've seen, the Japanese-labeled ones are usually just made for the Japan domestic market, so they tend to be cheaper because of how they're priced over there. The formula or quality is generally the same brand, just different packaging and language on the box lah. I would just double-check you're buying from a reputable seller, because the risk is less about fake and more about making sure it's been stored and shipped properly. Weighing it up, if the seller is trustworthy and the product looks legit, it's usually fine, but if you're unsure, the English-labeled ones sold here give you more peace of mind since you can read all the instructions clearly.
