Heck, I'd love a less bulky AirTag attachment for humans as well. My AirTag key ring is by far the biggest thing on my keychain (even bigger than my car keys), and it's so stiff that it often gets caught on other things on my pocket when I'm pulling my keys out. That never used to happen before.

This is probably the one aspect where Tile has been superior (for my use case). I never noticed the bulk of the Tile tracker on my keyring.

I'm keeping an eye out for less bulky attachments online. Everything I've seen so far emulates Apple's bulky keyring design.
