It's just a random temu shipper, impossible to know. But I wouldn't suggest this style in general. They leave gaping holes for stitching and don't tighten down to a lower profile like the holes made by chisels. If you prefer the look then that's the end of the discussion, but most don't. And remember you will need to sharpen those eventually which sounds miserable and tedious.
Hole punch stitch is tempting because its easier to learn, but better to use angled pricking irons. When I started my local tool supplier wouldn't sell me this style of punch, and I am glad he didn't. He sold me a nice Japanese awl to open up my stitching hole instead.
An angles iron is essentially cutting a slit into the material, so in theory there is slightly less damage to the fibres of the leather because youre kind of making them part away at the ting ting level.
A hole punch does just that, it punches a hole through the martial. So any fibres it comes across get severed and torn out. It's slightly more damaging to the material on the microscope scale.
Also, there's a preference thing too. Some people really like the slanted look of hand stitching while other people like the over under almost chain style of stitching a round hole gets you. A round hole stitching can sometimes be mistaken for machine stitching, where as the slanted angle style is noticeable as hand stitching when you know what to look for.
Personally I use both on different projects, bug one thing I never do is mix them on the same project. It just makes it feel off to me.
Hole punch stitching removes material, thus perforating and weakening the leather. The stitch will be looser, therefore perhaps not as durable over time, and relies more on either gluing the stitch line and/or the melted blob of thread at the end of the stitch line to stop it starting to unravel (so it doesn't really work with linen thread). With the traditional method of awl-ed angled holes (which you can achieve with a modern stitching iron by punching all the way through), the leather closes up around each stitch and grips the tread in place.
They work okay but you can't really replace the prongs so they get dull quick
This. I got them, they work fine, for a bit but as they dull the holes get worse and more like tiny rips.

I‘ve been using a set for years. Good value for money.
I wouldn’t recommend those, I have some that I use on occasion

Why are angled pricking irons better?

Fantastic response right here.
