This is a bottle and paper cap for "Hamilton," a lactic acid drink sold by Isoda Dairy in Tochigi Prefecture. I believe I obtained this at a flea market over 25 years ago. It's old, so there's some dirt and wear, but overall, it's in good condition. Please check the photos for the detailed condition and size of the item. It will be shipped via courier service. Please read and agree to the contents of the profile section. We look forward to your purchase.
