This time I did a web search about a product code this was over an alligator clip of BRYMEN.
But this was not a product code, it was
a patent number, and search results pointed directly at
hongkai-tw factory.
hongkai-tw, Keelung City 206, Taiwan (R.O.C.)
http://www.hongkai-tw.com/hongkai_web/emain.asp This website standing from 2010, very old web design.
But under the hood, there is motion, at the pages written in Chinese, they are there even PDF drawings of 2019.
There is also a second website, much fresher web design, poor product descriptions
Chen Wang Co. Taiwan.
https://www.chenwang.com.tw/en-index.php With a bit of patience, you will discover test leads and accessories, which they are distributed under other brands worldwide.
I will not give more details, because I will spoil the surprise.

An interesting manufacturing detail, all well made alligator clip with 2mm socket, they have a gold plated female insert, this protects probe tips from abrasion and damage.
While the rest alligator clip this is made of nickel plated iron.
