Perhaps, there are two lock factories in the lock core market of Meribao, and the trademark holder is not from Meribao lock factory. Now it is quite chaotic. However, I can suggest that you buy a good quality lock core, such as Jiabao super C-class blade lock core, which is of very good quality and the most advanced anti-theft performance, and the lock cores of Mody Lechang Enwanjia Li Hong are all good.
