I suggest you buy a big brand! If there is a problem, you can return it, which is more secure!

You can choose famous domestic brands (such as Chow Tai Fook, Caibai and Laofengxiang), and you must find a member of Platinum (Pt) Association! (Because you want to buy platinum)

Look at the metal mark of Pt on the product you choose! ! So the department will buy Pd! !
