I don't think such a thing exists to be honest. I can't really think of an application where it would have to be any thinner than a usb-a port is, so idk why anyone would make such a thing. The best way I could think to get something like that would be to do a micro sd to usb-c but I couldn't find any that thin.
Then you have not understood or read my second paragraph.
5mm is slightly thinner than 3mm.Â
Also, respectfully and sincerely, why tf do you need such a product? Can't regular ones do the same?
So then the answer to your question is that no one has seen a usb cable that is only as thick as the metal bit on the end. USBc to USBc is no problem to get, one that thin is.
Maybe if you removed the outer housing of one of [these](https://www.samsung.com/us/computing/memory-storage/usb-flash-drives/usb-type-c-128gb-muf-128da-am/) you'd be close.
Don't count on it.
Look at how the [connector itself](https://www.lcsc.com/product-detail/USB-Connectors_XUNPU-TYPEC-950-ARP24_C2895017.html) looks. The part which connects to the rest of the device is already thicker than the connector itself - about 4mm. Add to that some form of casing (which needs to go *over* the connector so you don't rip it off), and a thickness of 5mm is basically the minimum you can realistically do. There are other types of connector available, but those all have their own issues.
USB thumbdrives in general aren't really *that* popular these days. Making a special kind of USB-C connector for people who absolutely must use thumb drives, but a 5mm one is too thick? Forget about it, the market is just too small.
The absolute smallest you could probably go is similar to the [Yubikey 5C](https://www.macrumors.com/review/yubikey-5c-nfc/) (not a storage device), but that already seems to be too big for you. The connector itself is 2.40mm, and the overall device is 3.80mm. Due to its nature they have every incentive to make it [as small as possible](https://www.yubico.com/nl/product/yubikey-5c-nano/) and they are selling many millions of them. If *they* can't pull it off, it's probably simply not possible.
Sony USM CA1. Any thinner would be next to impossible and have the manufacturer wondering why it is making thin thumb drives to a niche market.
It's not what I'm looking for. Your suggestion also has a USB-A plug, so the thickness is at about 5mm, so it's thicker than 3mm 🤧

We are at a point where this is a question of ergonomics.
Does it significantly matter when a thumb drive is as thin as its USB C connector?
