Hey folks, I have 10-12 cases of old style returnable bottles. They are thicker and stronger than disposable bottle. Some even have the label(Black Label) on the bottle, some are Rolling rock pony bottles, Labatt's squat bottles. Some of the bottles look great while others have been around the bar a time or 2. The boxes are the stronger type boxes. I would recommend Oxyclean to ensure cleanliness, some have had beer in them too long. All are rinse out though. I am located in Catonsville, MD 21228
