I bought 9 bags, 450pcs(50pcs in a bag). I have to open at least one bag to check when arrived today or tomorrow.
The weight of one bag is 52.5g, so 9 bags is 473g. Plus package, it may exceed the 500g limit, so I may have to ship 400pcs.
I've just search "2DW232" and "Shanghai 17th Radio Factory"(in Chinese) and got 7 entries, all the sellers are in Shanghai.
The 1st is the one I bought(having bought 5 times), The 2nd have been bought 1 time.
I've once try to put Chinese here but it won't allowed by the forum, but here I try again for Shanghai 17th Radio Factory:

Edit: the above two faces plus two "?" were in Chinese but showed incorrectly.
