IMS bearing replacement tools, required?

[78F350]

I used my IMS tool: "LN Engineering Engine Intermediate Shaft Bearing Tool Set 1060813" that I purchased on Amazon. I tried a few wrong ways first, then managed to successfully extract the bearing from my 'practice engine' and reinstall it.
I am wondering if my tool kit is actually a counterfeit. The box was sealed and had all of the correct labeling, but my cat can do better welds.


I'd have my cat repair it, but even with the welds broken, it worked fine.

I suppose that to a counterfeiter it actually is just $20 in metal chunks.
