I have a K6 and it fits fine in a backpack. A bit heavy. I don’t generally travel with it but if I did I’d probably choose one of the many low profile 65% instead.

Build quality, like others have probably said, you can’t go wrong with Keychron, and they have mac keys. If you just want to get the one kb for your use case and not interact with the hobby beyond that, they’re who I’d chose from.

This seems almost unfairly cheap for something handpainted.

Explaining a joke is a lot like dissecting a frog.
