The first thing to judge whether a Yong brand hot water bottle is true or false is to look at the turnbuckle. Generally, the turnbuckles of old Yong brand hot water bottles are all metal. If it's old but plastic, it may be a fake. Of course, the new brand Yong hot water bottle has also been replaced with a rubber buckle. This method is mainly aimed at the old.
The second is the smell. Yongzi brand hot water bottle is made of good material, even if it is new, it will not have a strong rubber smell. If it is found to be too pungent or strong, it may be a fake.
Shanghai Yongzi brand hot water bottle can't be found in official website for the time being, and it is mainly purchased through physical stores or channels such as Tmall and Taobao. The price will not be very expensive, depending on the specific style and discount.
Yongzi brand hot water bottle is a classic product. It is suggested that you choose regular channels to buy as much as possible, so as to ensure product quality, avoid buying fakes and avoid waste.
